Looking Forward to Exciting Physics at the LHC: Recent Theory Advances on Neutrinos, QCD and Dark Matter
Physics searches and measurements at high-energy collider experiments traditionally focus on the high-pT region. However, for light particles, this emphasis may be misguided, as these particles tend to be highly collimated around the beam line. With FASER and SND@LHC, an experimental program has emerged in recent years to exploit this opportunity, expanding the LHC's physics potential by searching for feebly interacting particles as well as studying neutrino and muon interactions at TeV energies. comes with a variety of theoretical challenges, including the modeling of high-rapidity particle production, precision high-energy neutrino DIS, and dark sector particle phenomenology. In this talk, I will present recent theoretical advances addressing these questions. I will further discuss the potential of this emerging forward physics program to offer unique insights into forward particle production, probe proton structure in otherwise inaccessible regimes, address unresolved issues in astro-particle physics, and search for a diverse array of new particles.
