    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. …”

    The two-loop coefficient functions for double deeply virtual Compton scattering by Vladimir M. Braun, Hua-Yu Jiang, Alexander N. Manashov, Andreas von Manteuffel

    Published 2025-01-01
    “…Abstract Making use of conformal symmetry of large-n f QCD in d = 4 – 2ϵ dimensions at the Wilson-Fischer fixed point, we calculate the two-loop coefficient functions in the operator product expansion of two electromagnetic currents in general kinematics with two different photon virtualities. This result is necessary for the description of the double deeply virtual Compton scattering to the next-to-next-to-leading order accuracy, but is also interesting for a range of other two-photon processes. …”
