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...
28. Charged Lepton Flavour Violating Meson Decays in Seesaw Models
Parallel talk

The occurrence of neutrino oscillations demands the existence of flavour violation in charged lepton sector. The relation between the branching ratios of different
charged lepton flavour violating (CLFV) decay modes depends on the details of the neutrino mass model. In this work, we consider the three types of simple seesaw mechanisms
of neutrino masses and study the correlation between 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.
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.
39. Mass spectrum of ground state heavy-light mesons in relativistic independent quark model
Parallel talk

The confining strength or model parameters and constituent quark masses are determined after fitting the ground state masses with experimental data of respective mesons. We analyzed these from the hyperfine splitting of heavy-light and heavy flavored ground state mesons in the framework of relativistic independent quark (RIQ) model with one gluon exchange and centre of mass correction. For the...
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...
47. Measurements of lepton-flavour universality in semileptonic $B$ decay at Belle II
Parallel talk

The first run of the Belle II experiment collected a 365 fb$^{-1}$ 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, constrained initial state kinematics and excellent lepton identification, are an ideal environment to study lepton-flavour universality in semileptonic decays of the...
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...
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...
50. Rare and baryonic decays of charmed hadrons at Belle and Belle II
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...
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...
51. Studies of hadron spectroscopy at Belle and Belle II
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...
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...
46. The role of nonperturbative dynamics in D-meson mixing
Parallel talk

The theoretical predictions for the $D-\bar{D}$ mixing parameters fall significantly short of experimental measurements, with discrepancies spanning several orders of magnitude. This divergence is largely attributed to the Glashow–Iliopoulos–Maiani (GIM) mechanism, which suppresses leading-order contributions. However, higher-order corrections and nonperturbative effects have the potential to...
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...
