Long-lived Particles Anomaly Detection with Parametrized Quantum Circuits

Effects of Final State Interactions on Landau Singularities

This paper investigates how final-state rescattering influences triangle singularities that mimic resonance line-shapes, employing both Landau equations and a modern scattering formalism that incorporates explicit two- and three-body unitarity.

Prospects of five-dimensional $L_\mu-L_\tau$ gauge interactions in the light of elastic neutrino-electron scatterings: The scope of the DUNE near detector

This paper investigates the potential of the DUNE near detector to probe a five-dimensional $U(1)_{L_\mu - L_\tau}$ gauge extension of the Standard Model, which addresses the muon $(g-2)$ anomaly, by analyzing elastic neutrino-electron scattering data to explore MeV-scale parameter spaces and interference effects between multiple massive gauge bosons.

IAFormer: Interaction-Aware Transformer network for collider data analysis

The paper introduces \texttt{IAFormer}, a novel Transformer-based architecture that leverages boost-invariant pairwise quantities and a dynamic sparse "differential attention" mechanism to achieve state-of-the-art classification performance on collider data with over an order of magnitude greater computational efficiency than existing Particle Transformer models.

Comments on Exploring Quantum Statistics for Dirac and Majorana Neutrinos using Spinor-Helicity technique (arXiv:2507.07180 [hep-ph])

This paper critiques a recent study (arXiv:2507.07180) by arguing that its proposed ad-hoc symmetrization of Dirac neutrino amplitudes lacks physical justification and incorrectly violates lepton number conservation within the Standard Model.

Accessing nucleon transversity with one-point energy correlators

This paper proposes using the one-point energy correlator (OPEC) in transversely polarized proton-proton collisions as a novel, infrared-and-collinear safe method to probe the nucleon's transversity distribution with a clean angular asymmetry over a wider kinematic range than traditional hadron transverse momentum measurements.

Bayesian Constraints on Pre-Equilibrium Jet Quenching and Predictions for Oxygen Collisions

This paper employs a Bayesian analysis of a semi-analytic jet quenching framework coupled with hydrodynamics and pre-equilibrium energy loss to constrain early-time quenching mechanisms in large systems and predict significant jet and hadron suppression in future oxygen-oxygen collisions.

Charge carrier generation in RNDR-DEPFET Detectors

This paper presents the experimental characterization of a $64\times64$ RNDR-DEPFET pixel detector, highlighting its deep sub-electron noise performance, high time resolution, and suitability for the DANAE experiment's search for light dark matter via electron recoil detection.

Branching fraction measurement of the $\mathit{\Lambda} \to p \mu^- \overline{\nu}_{\mu}$ decay

Using 13 TeV proton-proton collision data from the LHCb experiment, researchers measured the branching fraction of the $\Lambda \to p \mu^- \overline{\nu}_{\mu}$ decay with twice the precision of previous results, finding it consistent with Standard Model predictions and providing a stringent test of lepton flavour universality in $s \to u$ transitions.

NO LESS: Novel Opportunities for Light Exotic Searches at the SPS

This paper demonstrates that a minimally reconfigured version of CERN's existing NA62 experiment, operating in a future ECN3 beam-dump facility with an optimized geometric setup, can achieve highly competitive sensitivity for detecting feebly interacting particles in the MeV to GeV mass range immediately upon beam availability.
