The FASER Experiment at the LHC

FASER is a small experiment designed to search for light and weakly-coupled particles during Run-3 of the LHC. Such particles, predicted in many extensions of the Standard Model, may be copiously produced along the beam collision axis and travel a significant path before decaying to detectable particles. FASER, conveniently located 480 m downstream of the interaction point of the ATLAS experiment, is designed to look for such signatures. The FASER location, its detector layout, and commissioning towards data-taking in 2022 are reviewed.
Keywords: collider physics, FASER, weakly-coupled particles.

Helmholtz Institute. Mainz, Staudingerweg 18, 55128 Mainz, Germany Received January 16, 2022
The PANDA experiment is one of the major projects in preparation at the upcoming Facility for Antiproton and Ion Research (FAIR) in Darmstadt/Germany. A multipurpose high energy physics detector is currently under construction and will be operated at the High Energy Storage Ring (HESR) of FAIR. The physics program includes hadron spectroscopy, search for charm and strangeness in nuclei, hypernuclear physics, nucleon structure and other QCD topics. In this report, some important aspects of the planned physics program of the PANDA experiment are described.
Keywords: collider physics, hadron spectroscopy, QCD.

Ecole Polytechnique Fédérale de Lausanne (EPFL), Lausanne, Switzerland Received April 1, 2022
We review four most precise measurements from charm physics program at the LHCb during 2021. These include the first observation of non-zero mass difference between neutral charm-meson eigenstates, the world most precise determination of both time-dependent and time-integrated charge-parity.
Keywords: LHCb, Charm physics, Charge-Parity violation.

Spectroscopy at LHCb
Paolo Gandini (on behalf of the LHCb Collaboration) E-mail: paolo.gandini@cern.ch
INFN - Sezione di Milano Received April 1, 2022
We will review the most recent results on hadron spectroscopy at the LHCb experiment at CERN. The LHCb experiment is a single-arm forward spectrometer with excellent tracking and particle identification capabilities. With its high luminosity, the experiment has proven to be a very prolific player in the search and observation of new states (both conventional and exotic) in the recent years.
Keywords: LHCb, Flavour, Spectroscopy.
