abstract

A search for new long-lived particles decaying to leptons using proton-proton collision data produced by the CERN LHC at $\sqrt{s}$ = 13 TeV is presented. Events are selected with two leptons (an electron and a muon, two electrons, or two muons) that both have transverse impact parameter values between 0.01 and 10 cm and are not required to form a common vertex. Data used for the analysis were collected with the CMS detector in 2016, 2017, and 2018, and correspond to an integrated luminosity of 118 (113) fb$^{-1}$ in the ee channel (e$\mu$ and $\mu\mu$ channels). The search is designed to be sensitive to a wide range of models with displaced e$\mu$, ee, and $\mu\mu$ final states. The results constrain several well-motivated models involving new long-lived particles that decay to displaced leptons. For some areas of the available phase space, these are the most stringent constraints to date.

  1. Search for massive, long-lived particles in events with displaced vertices and displaced muons in $pp$ collisions at $\sqrt{s}=13.6$ TeV with the ATLAS experiment

    hep-ex 2026-03 conditional novelty 6.0 of 10

    No signal of displaced-vertex-plus-displaced-muon events is seen in 164 fb^-1 of 13.6 TeV pp data; ATLAS sets improved 95% CL limits on RPV SUSY higgsino and stop production.

  2. 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.

  3. Search for the pair production of long-lived supersymmetric partners of the tau lepton in proton-proton collisions at $\sqrt{s}$ = 13 TeV

    hep-ex 2026-01 accept novelty 5.0 of 10

    No long-lived staus are observed; CMS excludes stau masses up to 425 GeV at 50 mm lifetime (mass-degenerate) and decay lengths 21-94 mm / 6-333 mm at 200 GeV.

  4. 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.
