72. Analysis of B -> VV decays under SU(3) * spin
Parallel talk

The analysis of $B \to PP$ decays where $B = \{B^0, B^+, B_s^0\}$ and $P = \{ \pi, K \}$ under the flavor SU(3) symmetry (SU(3)$_F$) exhibits disagreement with the SU(3)$_F$ limit of the standard model at the level of 3.6 $\sigma$. The individual fits to $\Delta S$ = 0 and $\Delta S$ = 1 decay modes are good, whereas the combined fit assuming same diagrams for $\Delta S$ = 0 and $\Delta S$ = 1...
74. Analysis of B -> VV decays under SU(3) x spin
Ms Ipsita Ray
45. Analysis of Lambda_b to Lambda(*) nu nu decays in light of recent Belle-II B+-> K+ nu nu data
Parallel talk

The Belle-II experiment has recently reported the first measurement of $B^+ \to K^+ \nu \bar{\nu}$ decay which exceeds the Standard Model prediction by approximately 2.7σ. The deviation may indicate the
presence of new physics beyond the Standard Model in the $b \to s\nu \nu$ sector. Under this assumption, we study the hadronic $\Lambda_b \to \Lambda(\to p \pi)$and $\Lambda_b \to...
73. Anomalies in Hadronic B Decays: an Update
Parallel talk

The decays B->PP, where the pseudoscalar P is a pi or K, have been studied under the assumption of flavor SU(3) symmetry. The global fit reveals a 3.6 sigma discrepancy with the Standard Model. Separate fits for Delta S = 0 and Delta S = 1 decays find parameter sets that differ by a factor of 10, indicating a flavor SU(3) breaking of 1000%, significantly larger than the 20% breaking expected...

79. CP violation in tau decays into states with neutral kaons
Parallel talk

CP violation in the kaon system can manifest in decays to final states containing neutral kaons. This effect depends on the experimental setup and the applied cuts. We show that the measured time-integrated CP asymmetry depends on the specific decay process, as it is influenced by the experimental detection efficiency as a function of both the energy in the lab frame and the decay time of the...
24. CPV in K\to\mu\mu
Parallel talk

I will discuss the possibility to extract short-distance parameters from the integrated CP asymmetry in $K\to\mu^+\mu^-$, the interplay between $A_{\rm CP}(K\to\mu^+\mu^-)$ and other observables, and the prospects for measurement within an LHCb-like setup as a case study.
81. Determining the CP property of the higgs and top coupling via a novel jet substructure observable
Parallel talk

Determining the CP property of the Higgs boson is important for a precision test of the Standard Model as well as for the search for new physics. We propose a novel jet substructure observable based on the azimuthal anisotropy in a linearly polarized gluon jet that is produced in association with a Higgs boson at high energy hadron colliders, and demonstrate that it provides a new CP-odd...
111. Direct detection of ultralight dark matter with charged lepton flavor violation

I will discuss a class of ultralight dark matter models with charged-lepton-flavor violating couplings that can induce potentially observable time-dependent signals at the intensity frontier. I will highlight the sensitivity of current/future experiments and outline possible UV completions.
103. Electron EDM and Γ(μ → eγ) in the 2HDM
Parallel talk

We present the first complete two-loop calculation of the electric dipole moment of the
electron, as well as the rates of the lepton-flavor violating decays μ → e + γ and τ → e/μ +
γ, in the unconstrained two-Higgs doublet model. We include the most general Yukawa
interactions of the Higgs doublets with the Standard Model fermions up to quadratic order,
and allow for generic phases in the...

113. Global fits of the Unitarity Triangle within and beyond the Standard Model. Updates from the UTfit collaboration.
Parallel talk

Flavour physics represents a unique test bench for the Standard Model (SM). New analyses performed at the LHC experiments and new results coming from Belle II are bringing unprecedented insights into CKM metrology and new results for rare decays. The CKM picture provides very precise SM predictions through global analyses. We present here the results of the latest global SM analysis performed...
41. Heavy-flavour results from ATLAS experiment
Parallel talk

This talk will overview the recent results on heavy-flavour hadron production and decays and spectroscopy of heavy-flavour exotic states obtained with Run-2 data. It will cover the most precise measurement of the $B^0$ meson lifetime, measurement of charmed meson production cross-section, studies of resonant structures in di-charmonium spectrum.
59. High Precision, High Impact: The Storage Ring Proton EDM Quest for Physics Beyond the Standard Model
Parallel talk

The storage ring electric dipole moment (EDM) experiment is designed to probe one of the most profound mysteries in fundamental physics: the origin of CP violation beyond the Standard Model and its possible role in explaining the observed matter-antimatter asymmetry of the universe. By aiming to measure the proton EDM with a sensitivity of $10^{−29}\,e⋅{\rm cm}$, this experiment will improve...
105. Higher-Order Flavor Sum Rules: From Amplitudes to Observables
Parallel talk

In my talk, I will discuss the theory of higher-order flavor sum rules, with a focus on U-spin. In recent years, we have come to understand that flavor sum rules possess a rich mathematical structure. This insight has led to the development of a powerful formalism that enables the derivation of amplitude sum rules to arbitrary order in symmetry breaking—without the need for explicit...

Parallel talk

The ICARUS Collaboration is now entering its fifth year of continuing operations of the 760-ton liquid argon T600 detector. The T600 was overhauled at CERN after operations at the LNGS underground laboratory in Italy and moved to its present location at FNAL - as part of the Short-Baseline Neutrino (SBN) program - where it successfully completed its commissioning phase in June 2022. At FNAL...
107. Lattice QCD Calculation of Radiative Corrections to Meson Leptonic Decays

Precise tests of CKM unitarity provide a probe of physics beyond the Standard Model. Using the most precise determinations—$V_{ud}$ from superallowed nuclear $\beta$ decays and $V_{us}$ from leptonic and semileptonic decays—the first‑row sum $|V_{ud}|^{2}+|V_{us}|^{2}+|V_{ub}|^{2}$ deviates from unity by $2\text{–}3\,\sigma$. This tension emphasizes the need for further reductions in both...
104. Lattice study of $K\to\pi\pi$ decays

Recent status of lattice calculation of $K\to\pi\pi$ decay and $\varepsilon’$ by the RBC and UKQCD collaborations will be presented. We estimate various systematic errors that are not only from lattice calculation but also from some others such as perturbative QCD. We will discuss what systematic errors need to be reduced in order to reach the experimental precision and verify the...
67. Lorentz- and CPT-violating muon-electron conversion in the presence of a nucleus
Parallel talk

We consider the conversion of a muon to an electron in the presence of a nucleus, mediated by Lorentz- and CPT-violating electromagnetic (mass dimension five) or four-point quark-lepton (mass dimension six) interactions. Bounds are obtained based on the results of SINDRUM II, and sensitivity estimates are made for upcoming searches by Mu2e and COMET. In particular, the four-point...
48. Measurements of electroweak penguin and lepton-flavour violating $B$ decays to final states with missing energy at Belle and Belle II
Parallel talk

The Belle and Belle II experiments have collected a 1.2 ab$^{-1}$ sample of $e^+ e^-\to B\bar{B}$ collisions at a centre-of-mass energy corresponding to the $\Upsilon(4S)$ resonance. These data, with low particle multiplicity and constrained initial state kinematics, are an ideal environment to search for rare electroweak penguin $B$ decays and lepton-flavour-violating $B$ decays to final...
49. Measurements of hadronic $B$ decay rates at Belle and Belle II
Parallel talk

The Belle and Belle II experiments have collected a 1.2 ab$^{-1}$ sample of $e^+ e^-\to B\bar{B}$ collisions at a centre-of-mass energy corresponding to the $\Upsilon(4S)$. The study of hadronic $B$ decays in these data allow the precise measurement of absolute branching fractions and angular distributions of the decay products. These measurements provide tests of QCD and allow the generation...
26. Modelling Quark-Hadron Duality Violation in Inclusive $B\to X_c\ell\bar\nu$
Parallel talk

The Heavy Quark Expansion (HQE) is the main tool for calculating decay rates and kinematic moments of inclusive semi-leptonic $B$ meson decays. The HQE manifests as an Operator Product Expansion (OPE) in terms of powers of the inverse heavy bottom quark mass ($1/m_b$). Using the HQE, the CKM matrix element $V_{cb}$ has been extracted at percent-level precision from moments of inclusive $B\to...
97. New Physics from Light Scalars in Rare Kaon Decay
Parallel talk

We introduce and investigate the effects of a light scalar interacting with the
short-lived kaon and the $K_{S} \rightarrow \mu^{+}\mu^{-} $ decay. We use the results of searches performed at
kaon factories as well as the Standard Model predictions for this decay to constrain the
couplings of a ϕ particle with a mass $m_{\phi}$ of the order of MeV. We also examine the time evolution of the...
52. Observation of a family of all-charm tetraquarks with spin-2 and positive parity
Parallel talk

We present a comprehensive study of near-threshold structures in the J/\psi J/\psi mass spectrum using the fully reconstructed J/\psi J/\psi \rightarrow 4\mu final state, based on proton-proton collision data at \sqrt{s} = 13 and 13.6 TeV collected by the CMS experiment. With approximately four times more J/\psi pair candidates compared to the previous Run 2 dataset, the combined data sample...
35. Probing quantum decoherence using data from B meson decays
Parallel talk

The time evolution of neutral $B$ mesons plays a fundamental role in determining key parameters of flavor physics. While their behavior is typically analyzed under the assumption of perfect quantum coherence, interactions with the surrounding environment can induce $decoherence$. Such environmental effects on neutral meson systems can be effectively described within the framework of open...

Parallel talk

The Belle and Belle II experiments have collected a $1.6~\mathrm{ab}^{-1}$ sample of $e^+e^-$ collision data at centre-of-mass energies near the $\Upsilon(nS)$ resonances. These samples contain a large number of $e^+e^-\to c\bar{c}$ events that produce charmed mesons and baryons. We present searches for rare flavour-changing neutral current processes and measure several radiative decays of...
82. Results from the LEGEND-200 experiment in the search for neutrinoless double beta decay
Parallel talk

The discovery of Neutrinoless double beta decay (0νββ) would provide unambiguous evidence for the Majorana nature of neutrinos, lepton number non-conservation and a measurement of the absolute neutrino mass scale. The Large Enriched Germanium Experiment for Neutrinoless ββ decay (LEGEND) is a phased search for 0νββ in the 76Ge isotope with enriched high-purity germanium (HPGe) detectors. The...

70. Search for $B$ Mesogenesis and Dark matter at $BABAR$.
Parallel talk

We present the most recent $BABAR$ searches for reactions that could simultaneously explain the presence of dark matter and the matter-antimatter asymmetry in the Universe. This scenario predicts exotic $B$-meson decays into an ordinary-matter baryon and a dark-sector anti-baryon $\psi_D$ with branching fractions accessible at the $B$ factories.
The results are based on the full data set of...
36. Search for dark sector at BESIII
Parallel talk

The BESIII experiment is a symmetric $e^+e^-$ collider operating at c.m. energy from 2.0
to 4.95 GeV. With the world’s largest threshold production data set of $J/\Psi$ (10
billion), $\Psi(3686)$ (2.6 billion), and $20 fb^{-1}$ of D meson pairs from $\Psi(3770)$ decay,
we are able to search for various dark sectors produced in $e^+e^-$ annihilation and
meson decay processes. In this talk,...
37. Search for rare decays with charm data at BESIII
Parallel talk

The BESIII experiment has collected 2.6 billion of $\Psi(3686)$ events, 10 billion of $J/\Psi$
events, 20 $fb^-1$ of D meson pairs at 3.773 GeV, and 7.33 $fb^-1$ $D_sD_s^*$ events from 4.128
to 4.226 GeV. The huge data samples allow us to search for rare processes in charm
hadron decays. In this talk, we report the search for FCNC decay in $D_s^+\to h(h')e^+e^-$,
lepton number violation...
77. Semileptonic decays of heavy mesons to light hadronic resonances
Parallel talk

Semileptonic decays of heavy mesons into resonances are the next logical step to test the Standard Model and search for New Physics. We will present the lattice QCD framework and the first steps in calculating form factors in the $B\to\pi\pi\ell\bar{\nu}$ process to support this endeavor. Our calculation, at this point at a single pion mass (~320 MeV) and lattice spacing (~0.114fm), uses the...
62. Spontaneous CP Violation in an Axion Model: Implications for Leptonic Flavor and the Minimal Seesaw
Parallel talk

We investigate an extension of the Dine–Fischler–Srednicki–Zhitnitsky (DFSZ) axion model that realizes spontaneous CP violation and explores its implications for leptonic flavor structure within the framework of the minimal seesaw mechanism. By introducing singlet heavy Majorana neutrinos and an additional complex singlet scalar, we construct the extended Yukawa and scalar sectors necessary...

Parallel talk

The Belle and Belle II experiments have collected a $1.6~\mathrm{ab}^{-1}$ sample of $e^+e^-$ collision data at centre-of-mass energies near the $\Upsilon(nS)$ resonances. These data include a 19.2 fb$^{-1}$ sample of data collected at centre-of-mass energies near the $\Upsilon(10753)$ resonance. We present several scan results including $e^+e-\to \Upsilon(nS)\eta$. In addition, we present a...
68. The EDM of the electron in the decoupling limit of the aligned 2HDM
Parallel talk

We discuss model-independent contributions to the electron EDM, focusing on those contributions emerging from a heavy scalar sector linearly realized. To provide a concrete new physics realization, we investigate the aligned 2HDM in the decoupling limit. We point out that logarithmically enhanced contributions generated from Barr-Zee diagrams with a fermion loop are present in the aligned...
40. The Mu2e Experiment
Parallel talk

The Mu2e experiment, based at Fermilab, will search for the coherent, neutrino-less conversion of a negative muon into an electron in the field of an aluminum nucleus, an example of Charged Lepton Flavor Violation (CLFV). Observation of CLFV at Mu2e would be an unambiguous signal of physics beyond the Standard Model (BSM). Mu2e aims to improve upon the previous upper limit by four orders of...
25. Tripartite entanglement in B decays
Parallel talk

The tripartite entanglement between two spins and orbital angular momentum (OAM) has been previously discussed for Higgs decays into two vector bosons in 2403.13942. For B decays into two spin-one particles it is basically the same situation, though I never published it. I want to highlight the possibility of such measurements, using the data already published by experiments to calculate the...
