Forward Physics and QCD at the LHC and the EIC - 798 WE-Heraeus Seminar

Bad Honnef, Germany

Bad Honnef, Germany


Aims and scope of the 798. WE-Heraeus-Seminar:
Hadron production at very forward rapidities is studied in high-energy proton-
proton/ion scattering, lepton-proton/ion scattering, and cosmic ray physics and
represents a topic of common interest to these fields. The forward region offers
unique opportunities for exploring QCD in small-x and diffractive processes and to
search for physics beyond the Standard Model, but it also presents specific
experimental challenges in forward hadron detection. Important topics to be
discussed within QCD include double-parton scattering, diffraction, BFKL dynamics,
saturation, and the color glass condensate. Experimental signatures that will lead to a
better understanding of these phenomena are elastic and exclusive processes,
forward jet and particle production as well as vector meson, dilepton and photon
production. Relevant topics in the search for physics beyond the Standard Model are
anomalous couplings, axions and axion-like particles, neutrino properties and the
nature of dark matter. The improvement of theoretical predictions and optimization
of experimental observables will be central topics of discussion at this seminar. Its
purpose is therefore to bring together theorists and experimentalists in high-energy
collider experiments and cosmic ray physics, to review the status of forward physics,
discuss the opportunities and challenges, and realize synergies between the different
fields. Discussions will focus on theoretical predictions and their precision on the one
hand and on present experiments at the LHC and RHIC, the forward physics program
with the future EIC and FPF, and the connections with cosmic ray physics on the
other hand.
