Searching for light neutralinos with a displaced vertex at the LHC
Journal of High Energy Physics, 2022 We study a bino-like light neutralino ( χ ~ 1 0 $$ {\overset{\sim }{\chi}}_1^0 $$ ) produced at the LHC from the decay of a scalar lepton ( e ~ L $$ \tilde{e}_L $$ ) through the process pp → e ~ L $$ \tilde{e}_L $$ → e χ ~ 1 0 $$ e{\overset{\sim }{\chi ...

Journal of High Energy Physics, 2023 In this work, we propose a search for a single photon at FASER and FASER2, produced from decays of bino-like, sub-GeV lightest neutralinos in the theoretical framework of the R-parity-violating (RPV) Minimal Supersymmetric Standard Model (MSSM).

Sgoldstino signal at FASER: prospects in searches for supersymmetry
Journal of High Energy Physics, 2022 We investigate FASER@LHC perspectives in searches for light (0.1–5 GeV) sgoldstinos in models with low energy (10–104 TeV) supersymmetry breaking. We consider flavor conserving and flavor violating couplings of sgoldstinos to Standard Model fermions and ...

On (g − 2) μ from gauged U(1) X
Journal of High Energy Physics, 2022 We investigate an economical explanation for the (g − 2) μ anomaly with a neutral vector boson from a spontaneously broken U(1) X gauge symmetry. The Standard Model fermion content is minimally extended by 3 right-handed neutrinos.

New constraint on dark photon at T2K off-axis near detector
Journal of High Energy Physics, 2023 The T2K experiment is one of the most powerful long-baseline experiments to investigate neutrino oscillations. The off-axis near detector called ND280 is installed 280 m downstream from the neutrino production target to measure the neutrino energy ...

Leptophilic gauge bosons at lepton beam dump experiments
Journal of High Energy Physics, 2023 It has been recently known that we can use beams of future lepton colliders, the International Linear Collider (ILC), the Compact Linear Collider (CLIC), and the muon collider, for beam dump experiment if a shield and a detector are installed behind the ...

Displaced searches for light vector bosons at Belle II
Journal of High Energy Physics, 2022 With a design luminosity of 50 ab −1 and detectors with tracking capabilities extending beyond 1 m, the Belle II experiment is the perfect laboratory for the search of particles that couple weakly to the Standard Model and have a characteristic decay ...

Resolving the muon g − 2 tension through Z′-induced modifications to σ had
Journal of High Energy Physics, 2023 The QED hadronic vacuum polarization function plays an important role in the determination of precision electroweak observables and of the anomalous magnetic moment of the muon.
