The hierarchy between the electroweak scale and a few TeV may be the result of a new symmetry. In several models, including Folded SUSY, the symmetry partners of the quarks do not carry standard model color, making it more difficult for the LHC to discover them. However, new strategies can be used to detect these symmetry partners at the LHC. I describe how displaced decays can be used to...

CMB limits on isocurvature are often interpreted as excluding high-scale inflation with large QCD axion decay constants in pre-inflationary PQ models. We emphasize this can be evaded through non-flat PQ field-space geometry. In particular, a nonlinear sigma-model kinetic term, such as a hyperbolic field-space geometry, enhances the effective decay constant during inflation, suppressing...

This talk presents recent precision measurements of key properties of the Higgs boson using the full dataset of proton-proton collisions at √s = 13 TeV and 13.6 teV collected during Run 2 and Run 3, respectively, of the LHC by the ATLAS experiment. Recent projections done for the HL-LHC will also be discussed.

Various theories beyond the Standard Model predict new, long-lived particles with unique signatures which are difficult to reconstruct and for which estimating the background rates is also a challenge. Signatures from displaced and/or delayed decays anywhere from the inner detector to the muon spectrometer, as well as those of new particles with fractional or multiple values of the charge of...

Confining strings provide a useful window into nonperturbative gauge dynamics, and supersymmetric theories offer a controlled setting in which many of their properties can be studied analytically. In this talk, I will discuss recent progress on confining strings in softly deformed Seiberg-Witten theory, where dual superconductivity gives an explicit realization of electric flux tubes. I will...

We study the $l^-l^+\to \nu\bar{\nu}Zh$ process for future lepton colliders, whose cross section becomes larger than that for $l^-l^+\to Zh$ in the energy region above a few TeV.

LHC supersymmetric (SUSY) particle search limits are usually performed within the context of simplified models and subsequently interpreted within the 19 parameter phenomenological MSSM (pMSSM) as to how many models avoid search limits for a particular sparticle mass, often including WIMP dark matter constraints.
We provide a critical discussion of this procedure and how it can go

Many theories beyond the Standard Model predict new phenomena, such as heavy vectors or scalar, vector-like quarks, and leptoquarks in final states containing bottom or top quarks. Such final states offer great potential to reduce the Standard Model background, although with significant challenges in reconstructing and identifying the decay products and modelling the remaining background. The...

The non-leptonic $B$-meson decays serve as excellent ground to test the Standard Model of Particle Physics for example, how well are flavor symmetries such as isospin and flavor SU(3) realised in data, and their study is also important for new physics searches. As it has been observed, the analysis of $B \to PP$ decays where $B = \{B^0, B^+, B_s^0\}$ and $P = \{ \pi, K \}$ under the flavor...

Many new physics models predict the existence of resonant states decaying into two bosons, including the Higgs boson or new scalar S bosons. These processes provide crucial signatures in the search for physics beyond the Standard Model and may offer insights into the mechanism of electroweak symmetry breaking. In this talk, the latest results from searches for resonant Higgs boson pair (HH)...

ATLAS and CMS are measuring the Higgs production channel $pp \to hZ$, where $h$ is the Higgs boson discovered at the LHC. We analyze contributions of a CP-odd Higgs boson to this process via $gg \to A \to hZ$. This is done for $m_A \sim 95$ GeV, for Higgs bosons describing the $\gamma\gamma$ excesses observed at the LHC. We also analyze the more general scenario with $m_A \ge 200$ GeV and find...

We investigate a framework of the Minimal Supersymmetric Standard Model (MSSM) in which the quark and lepton flavor structure and suppression of flavor-changing neutral currents (FCNCs) are governed by non-invertible selection rules. By implementing such non-group-like fusion rules for matter fields, arising from gauging the outer automorphism $\mathbb{Z}_2$ of a discrete $\mathbb{Z}_N$...

We propose a class of dark matter models based on a chiral U(1) gauge symmetry acting on a dark sector. The chiral U(1) protects the masses of the dark sector fermions, and also guarantees the stability of the dark matter particle by virtue of an unbroken discrete N gauge symmetry. We identify 38 such U(1) models which are descendants of a chiral SU(3)×SU(2) gauge symmetry, consisting of a...

We examine the phenomenological implications of an additional invariant in the supersymmetric standard model. The construction modifies the supersymmetry algebra at the classical level and induces departures from conventional supermultiplet mass degeneracy without introducing explicit soft-breaking terms. We analyze the resulting mass terms in a minimal implementation and discuss how the...

ATLAS and CMS have observed consistent excesses in the search $pp \to \tilde{\chi}_2^0 \tilde{\chi}_1^\pm \to Z^*\tilde{\chi}_0^1\,W^{\pm *}\tilde{\chi}_0^1$. The favored mass ranges are $m_{\tilde{\chi}_2^0} \sim m_{\tilde{\chi}_1^\pm} \ge 200$ GeV and $\Delta m := m_{\tilde{\chi}_2^0} - m_{\tilde{\chi}_0^1} \approx 15-20$ GeV. We interpret these excesses in GUT based scenarios within the...

Dark matter and gravitons are unavoidably produced through their minimal gravitational coupling to a time-dependent cosmological background. During the reheating epoch, this production is sourced by the coherent oscillations of the inflaton field around the minimum of its potential. Two complementary frameworks have been widely employed to study this process: the Boltzmann approach, which...

In the Standard Model, the ground state of the Higgs field is not found at zero but instead corresponds to one of the degenerate solutions minimising the Higgs potential. In turn, this spontaneous electroweak symmetry breaking provides a mechanism for the mass generation of nearly all fundamental particles. Experimentally, the Higgs boson self-couplingm and thereby the shape of the Higgs...

One of the main open questions in particle physics is the baryon asymmetry in the universe (BAU). The mechanism of electroweak baryogenesis requires a strong first order electroweak phase transition (SFOEWPT) in the early universe that can only be realized in Higgs sector extension of the SM. We focus on the Real Higgs Singlet Extension (RxSM). In order to investigate the shape of the Higgs...

We revisit the electric dipole moments (EDMs) of quarks and leptons in the Minimal Supersymmetric Standard Model (MSSM) with trilinear $R$-parity violation (RPV). In this framework, EDMs are induced at the two-loop level via RPV interactions. We perform a comprehensive recalculation of several classes of Barr-Zee type diagrams in a general $R_\xi$ gauge. While we find general agreement with...

Although the simpliest extension to the Standard Model (SM), the real singlet scalar offers potential avenues for questions regarding electroweak (EW) baryogenesis due to its effects on the Higgs potential. Additionally, its relative simplicity makes it an advantageous model to analyze. As such, it is a worthwhile extension to pursue. For current LHC results as well as for the HL-LHC, and the...

Finding deviations in Higgs couplings is crucial to determine the nature of the underlying Higgs sector. Here the triple Higgs coupling (THC), $\lambda_{hhh}$, and the Higgs coupling to $Z$ bosons, $g_{hZZ}$, are of prime importance. We analyze the relevance of higher-order corrections in concrete UV-complete BSM models. We compare the reach of the HL-LHC and future $e^+e^-$ colliders in view...

We investigate the trilinear Higgs boson coupling derived from the functional forms of various extended Higgs potentials. In light of experimental constraints on Higgs boson couplings, we focus on extended Higgs models in which the trilinear Higgs boson coupling is predominantly determined by the Standard Model (SM) Higgs field. Such models include the nearly aligned Higgs effective field...

Superstring theory with flux compactifications results in an enormous number of vacua solutions each leading to different 4d laws of physics, collectively known as the string landscape. While the string landscape provides at present the only plausible explanation for the size of the cosmological constant, it may also predict the form of weak scale supersymmetry (SUSY) which is expected to...
