    Proposal to use LHC general-purpose detectors in “beam-dump” measurements for long-lived particles by Bhaskar Dutta, Doojin Kim, Hyunyong Kim

    Published 2025-02-01
    “…For proof of principles, we consider the axion-like particles (ALPs) produced via the Primakoff process in the presence of their interaction with photons at CMS. We argue that the drift tube chambers and the ME0 module of the muon system can serve as detectors to record the photons from the ALP decay, demonstrating that assuming the background level can be controlled as discussed in this work, the resulting sensitivity reach is competitive due to their close proximity to the signal source points. …”

    Polarization of thermal dilepton radiation by Florian Seck, Bengt Friman, Tetyana Galatyuk, Hendrik van Hees, Ralf Rapp, Enrico Speranza, Jochen Wambach

    Published 2025-02-01
    “…This allows, for the first time, independent tests of the longitudinal and transverse components of the virtual photon's selfenergy. While the low- and high-mass regions exhibit the expected limits of transverse and unpolarized photons, respectively, baryon-driven medium effects in the ρ-meson mass region create a marked longitudinal polarization that transits into a largely unpolarized emission from the quark-gluon plasma, thus providing a sensitive test of microscopic emission processes in QCD matter. …”

    PHENIX highlights: Recent results from PHENIX by Shimomura Maya

    Published 2025-01-01
    “…Additionally, forward rapidity J/ψ and v2 measurements show a result consistent with zero, in contrast to LHC findings. (2) Precise direct photon yields obtained via large statistical datasets, spanning a wide range of transverse momentum (pT) and centrality bins have the scaling behavior across various large systems, and non-prompt direct photon results reveal temperature (Teff) dependence on pT. (3) Charged hadron production was examined in collision systems of varying sizes, revealing that RAA is primarily dependent on the overlap volume (Npart). …”
