Abstract:

FASER, the ForwArd Search ExpeRiment, is located 480 m downstream of the ATLAS interaction point and exploits the intense forward particle flux to turn the LHC forward region into a new laboratory for neutrinos and new physics. FASER studies TeV-energy neutrinos, the highest-energy neutrinos ever observed from a human-made source—and searches for light, feebly interacting new particles. The energy and flavor spectra of these neutrinos also trace forward pion, kaon, and charm production, providing sensitivity to low-x QCD. Moreover, a 13.6 TeV proton–proton collision corresponds to a cosmic-ray proton of roughly 100 PeV striking a stationary proton, allowing FASER measurements to constrain atmospheric-neutrino predictions, particularly the prompt component from charm decays. Since the start of LHC Run 3 in July 2022, FASER has recorded 343 fb⁻¹ of collision data until the end of the run3. This talk will present the detector, current physics results, and future prospects.

Short bio:

Dr. Tomohiro Inada is an Assistant Professor at Kyushu University and an experimental physicist working at the interface between particle physics and astrophysics. He studies fundamental physics through cosmic observations and accelerator experiments. He received his Ph.D. from the University of Tokyo in 2020 and subsequently held positions as a Shuimu Tsinghua Scholar at Tsinghua University and an Experimental Physics Research Fellow at CERN. His work has received national recognition through several early-career awards from both astroparticle physics and high-energy physics communities in Japan, in addition to Outstanding Postdoctoral Fellow Finalist Award at Tsinghua University.. His research uses the forward region of the LHC to study collider neutrinos and search for weakly interacting new particles. He currently serves as FASER Tracker Project Leader and a member of the FASER Executive Board, contributing to physics analyses, detector operations, and future upgrades.
