Phenomenology of Inflaton-Driven Early QCD Confinement and Solution to Axion Isocurvature Problem

This paper proposes a mechanism where an inflaton-gluon coupling dynamically raises the QCD confinement scale during inflation to suppress axion isocurvature perturbations, subsequently allowing the axion to become light and generate the observed dark matter abundance, with viability ensured through specific reheating scenarios and supersymmetry.

Proposal for a shared transverse LLP detector for FCC-ee and FCC-hh and a forward LLP detector for FCC-hh

This paper proposes the design of two dedicated long-lived particle (LLP) detectors, DELIGHT and FOREHUNT, for the Future Circular Collider (FCC) facility, featuring a novel shared transverse detector for both FCC-ee and FCC-hh runs to optimize costs and significantly enhance sensitivity to elusive new physics.

When backgrounds become signals: neutrino interactions in xenon-based dark matter detectors

This paper analyzes recent electron and nuclear recoil data from XENONnT, PandaX-4T, and LUX-ZEPLIN to probe both Standard Model and Beyond the Standard Model physics, highlighting how xenon-based dark matter detectors can uniquely complement dedicated neutrino experiments by providing sensitivity to solar neutrino interactions and flavor-dependent new physics effects.

Sub-GeV dark matter and multi-decay signatures from dark showers at beam-dump experiments

This study evaluates the potential for SHiP and Belle II to detect sub-GeV dark matter through multi-displaced vertex signatures arising from dark showers in strongly-interacting dark sectors, identifying a significant parameter space where such signals could reveal the structure of the dark sector.
