Effects of threshold resummation for large-xx PDF in large momentum effective theory

This paper investigates large-xx parton distribution functions within large momentum effective theory by factorizing the matching coefficient into hard and soft components to resum threshold double logarithms and leading renormalons, demonstrating that perturbative matching remains reliable when both active and spectator quark momenta significantly exceed the QCD scale.

New Physics Through Flavor Tagging at FCC-ee

This paper proposes an optimal analysis leveraging machine learning-based flavor tagging at the FCC-ee to achieve unprecedented precision in measuring hadronic cross-section ratios, thereby significantly enhancing sensitivity to flavor non-universal and flavor-violating four-fermion interactions within the SMEFT framework and simplified models addressing BB-meson anomalies.

Neutralino dark matter in gauge mediation

This paper investigates the viability of neutralino dark matter within five-dimensional gauge-mediated supersymmetry breaking models with a O(100)\mathcal{O}(100) TeV gravitino, analyzing four distinct scenarios to determine their allowed parameter spaces, consistency with experimental limits, and prospects for detection at the HL-LHC and direct detection experiments.

CP violation studies at Super Tau-Charm Facility

This report discusses the prospects for sensitive tests of Standard Model predictions and searches for new physics through unique studies of CP violation in charmed hadrons, hyperons, and tau leptons, as well as CPT invariance tests in neutral kaon mixing, at a future high-luminosity Super Tau-Charm Facility operating between 2.0 and 7.0 GeV.

Proposed measurement of longitudinally polarised vector bosons in WHWH and ZHZH production at Hadron colliders

This paper proposes and evaluates analysis strategies using kinematic observables and machine learning to measure longitudinally polarized WW and ZZ bosons in associated Higgs production at the LHC, projecting that the High-Luminosity LHC will achieve 5σ\sigma discovery significance and percent-level cross-section precision for these states in the H→bbˉH \to b\bar{b} and H→γγH \to \gamma\gamma channels.

Substructure grooming of inclusive and photon-tagged jets in heavy-ion collisions

This paper presents a theoretical study using the SHELL transport model showing that the suppression of high relative transverse momentum in groomed jet substructures in heavy-ion collisions arises from partonic energy loss and selection bias, while the broadening of the groomed jet radius in photon-tagged jets provides direct evidence of medium-induced gluon radiation effects.

Multimessenger Constraints on Production Sites of High-Energy Neutrinos from NGC 1068

This paper utilizes multimessenger constraints from IceCube and Fermi-LAT data to demonstrate that hadronuclear ($pp$) processes in NGC 1068 allow for a larger neutrino emission region compared to photohadronic scenarios, while also challenging shock acceleration models that require cosmic-ray spectra extending to 1 GeV with spectral indices sCR≳2s_{\rm CR} \gtrsim 2.
