LFV searches by ATLAS and CMS experiments by Luca Fiorini

“…The appearance of lepton-flavour-violating processes in LHC proton-proton collisions is one of the possible ways that new physics beyond the Standard Model could manifest itself. This proceeding summarizes the most recent searches for lepton-flavour-violating processes and tests of lepton flavour universality with the ATLAS and CMS detectors, using proton-proton collisions at a centre-of-mass energy of 13 TeV.…”

Leptophilic portals to new physics at colliders by P. S. Bhupal Dev

“…Therefore, searches for lepton flavor violation (LFV) are promising probes of new physics beyond the Standard Model. High-energy colliders provide a powerful tool to study LFV effects, which are complementary to the low-energy charged LFV searches. …”

Lepton flavor violation at FCC-ee and CEPC by Pankaj Munbodh

“…Therefore, if observed, lepton flavor violation would be a clear indication of new physics beyond the Standard Model. We study the process $e^+e^-\to\tau\mu$ at tree-level in the Standard Model Effective Field Theory both on the $Z$-pole and at higher center-of-mass energies. …”

Gravitational Waves: Echoes of the Biggest Bangs Since the Big Bang and/or BSM Physics? by John Ellis

“…The discovery of gravitational waves has opened new windows on astrophysics, cosmology and physics beyond the Standard Model (BSM). Measurements by the LIGO, Virgo and KAGRA Collaborations of stellar–mass binaries and neutron star mergers have shown that gravitational waves travel at close to the velocity of light and constrain BSM possibilities, such as a graviton mass and Lorentz violation in gravitational wave propagation. …”

Point cloud-based diffusion models for the Electron-Ion Collider by Jack Y. Araz, Vinicius Mikuni, Felix Ringer, Nobuo Sato, Fernando Torales Acosta, Richard Whitehill

“…At high-energy collider experiments, generative models can be used for a wide range of tasks, including fast detector simulations, unfolding, searches of physics beyond the Standard Model, and inference tasks. In particular, it has been demonstrated that score-based diffusion models can generate high-fidelity and accurate samples of jets or collider events. …”

Exploring potential Higgs resonances at 650 GeV and 95 GeV in the 2HDM Type III by R. Benbrik, M. Boukidi, K. Kahime, S. Moretti, L. Rahili, B. Taki

“…Through a detailed analysis, we demonstrate that these two signals can be fitted simultaneously at the 2.5σ significance level, offering a promising solution to the observed anomalies and potentially hinting at new physics Beyond the Standard Model (BSM).…”

<i>g</i>-Factor Isotopic Shifts: Theoretical Limits on New Physics Search by Dmitry S. Akulov, Rinat R. Abdullin, Dmitry V. Chubukov, Dmitry A. Glazov, Andrey V. Volotka

“…The isotopic shift of the bound-electron <i>g</i> factor in highly charged ions (HCI) provides a sensitive probe for testing physics beyond the Standard Model, particularly through interactions mediated by a hypothetical scalar boson. …”
