The MATHUSLA detector is a simple large-volume tracking detector to be located on the surface above one of the general-purpose experiments at the Large Hadron Collider. This detector was proposed in [1] to detect exotic, neutral, long-lived particles that might be produced in high-energy proton-proton collisions. In this paper, we consider the use of the limited information that MATHUSLA would provide on the decay products of the long-lived particle. For the case in which the long-lived particle is pair-produced in Higgs boson decays, we show that it is possible to measure the mass of this particle and determine the dominant decay mode with less than 100 observed events. We discuss the ability of MATHUSLA to distinguish the production mode of the long-lived particle and to determine its mass and spin in more general cases.

  1. Complete Light Long-Lived Particles searches in Type-I 2HDM

    hep-ph 2025-08 unverdicted novelty 6.0 of 10

    In the Type-I 2HDM, light long-lived Higgs particles are forced into a narrow relation between mixing angle and tanβ, and FASER2 could probe the benchmark regions about a hundred times better than FASER.

  2. Probing Dark Matter freeze-in with long-lived particle signatures: MATHUSLA, HL-LHC and FCC-hh

    hep-ph 2019-08 conditional novelty 6.0 of 10

    Projected MATHUSLA, HL-LHC, and FCC-hh forward detector sensitivities probe Higgs-mediated freeze-in dark matter across parent masses up to about 10 TeV.

  3. Inverse Weak measurement in SERF magnetometer

    physics.ins-det 2025-08 unverdicted novelty 5.0 of 10

    A SERF magnetometer with inverse weak measurement readout is claimed to reach 182.8 femtotesla per root hertz and improve long-term stability by one to two orders of magnitude.
