Searching for Gluino LSP at the LHC
Paulina Knees, Essodjolo Kpatcha, Iñaki Lara +4
We analyse relevant signals expected at the LHC, assuming that the gluino is the lightest supersymmetric particle (LSP) in the framework of the SSM. In this -parity violatin…
New Constraint on Dark Photon at T2K Off-Axis Near Detector
Takeshi Araki, Kento Asai, Tomoya Iizawa +3
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…
Search for Lepton Flavor Violating Decay at FASER
Takeshi Araki, Kento Asai, Hidetoshi Otono +2
FASER is one of the promising experiments which search for long-lived particles beyond the Standard Model. In this paper, we consider charged lepton flavor violation (CLFV) via a l…
QCD Axion Search with ILC Beam Facility
Hajime Fukuda, Hidetoshi Otono, Satoshi Shirai
One of the most promising methods to search for axions is a light-shining-through-walls (LSW) experiment. In this work, we discuss the possibility of performing an LSW experiment a…
Searching for stop LSP at the LHC
Essodjolo Kpatcha, Iñaki Lara, Daniel E. López-Fogliani +3
We analyze relevant signals expected at the LHC for a stop as the lightest supersymmetric particle (LSP). The discussion is carried out in the framework of the SSM, where the p…
The Forward Physics Facility: Sites, Experiments, and Physics Potential
Luis A. Anchordoqui, Akitaka Ariga, Tomoko Ariga +78
The Forward Physics Facility (FPF) is a proposal to create a cavern with the space and infrastructure to support a suite of far-forward experiments at the Large Hadron Collider dur…
Dark Photon from Light Scalar Boson Decays at FASER
Takeshi Araki, Kento Asai, Hidetoshi Otono +2
FASER is one of the promising experiments which search for long-lived particles beyond the Standard Model. In this paper, we focus on dark photon associating with an additional U(1…
Cornering Higgsino: Use of Soft Displaced Track
Hajime Fukuda, Natsumi Nagata, Hideyuki Oide +2
Higgsino has been intensively searched for in the LHC experiments in recent years. Currently, there is an uncharted region beyond the LEP Higgsino mass limit where the mass splitti…
Sampling the SSM for displaced decays of the tau left sneutrino LSP at the LHC
Essodjolo Kpatcha, Inaki Lara, Daniel E. Lopez-Fogliani +4
Within the framework of the SSM, a displaced dilepton signal is expected at the LHC from the decay of a tau left sneutrino as the lightest supersymmetric particle (LSP) with a…
FASER's Physics Reach for Long-Lived Particles
FASER Collaboration, Akitaka Ariga, Tomoko Ariga +25
FASER,the ForwArd Search ExpeRiment,is a proposed experiment dedicated to searching for light, extremely weakly-interacting particles at the LHC. Such particles may be produced in…
Looking for the left sneutrino LSP with displaced-vertex searches
Inaki Lara, Daniel E. Lopez-Fogliani, Carlos Munoz +3
We analyze a displaced dilepton signal expected at the LHC for a tau left sneutrino as the lightest supersymmetric particle with a mass in the range - GeV. The sneutrinos…
Searching for Metastable Particles with Sub-Millimeter Displaced Vertices at Hadron Colliders
Hayato Ito, Osamu Jinnouchi, Takeo Moroi +2
A variety of new-physics models predict metastable particles whose decay length is mm. Conventional displaced-vertex searches are less sensitive to this sub-millimeter…
FASER: ForwArd Search ExpeRiment at the LHC
Jonathan L. Feng, Iftah Galon, Felix Kling +1
New physics has traditionally been expected in the high- region at high-energy collider experiments. If new particles are light and weakly-coupled, however, this focus may be…
Higgsino Dark Matter or Not: Role of Disappearing Track Searches at the LHC and Future Colliders
Hajime Fukuda, Natsumi Nagata, Hidetoshi Otono +1
Higgsino in supersymmetric standard models is known to be a promising candidate for dark matter in the Universe. Its phenomenological property is strongly affected by the gaugino f…
Extending the LHC Reach for New Physics with Sub-Millimeter Displaced Vertices
Hayato Ito, Osamu Jinnouchi, Takeo Moroi +2
Particles with a sub-millimeter decay length appear in many models of physics beyond the Standard Model. However, their longevity has been often ignored in their LHC searches and t…
Cornering Compressed Gluino at the LHC
Natsumi Nagata, Hidetoshi Otono, Satoshi Shirai
We discuss collider search strategies of gluinos which are highly degenerate with the lightest neutralino in mass. This scenario is fairly difficult to probe with conventional sear…
New probes for bino dark matter with coannihilation at the LHC
Hidetoshi Otono
It has been widely known that bino-like dark matter in supersymmetric theories suffers from over-production. The situation can be improved if the gluino or wino has a mass of O(10)…
Probing Bino-Wino Coannihilation at the LHC
Natsumi Nagata, Hidetoshi Otono, Satoshi Shirai
We study bino-wino coannihilation scenario in the so-called spread or mini-split supersymmetry. We show that, in this model, a neutral wino has a macroscopic decay length in a wide…
Probing Bino-Gluino Coannihilation at the LHC
Natsumi Nagata, Hidetoshi Otono, Satoshi Shirai
It has been widely known that bino-like dark matter in the supersymmetric (SUSY) theories in general suffers from over-production. The situation can be drastically improved if glui…
