79. Semi-hard reactions at the Forward Physics Facility

Michael Fucilla (Università della Calabria)

Forward emissions represent a unique opportunity to test perturbative QCD in new, and so far unexplored, kinematical regimes. In the semi-hard regime, where $s>>Q^2>>\Lambda_{QCD}$, pure fixed-order predictions need to be supplemented by an all-order resummation which takes into account the effect of large energy-type logarithms. The Balistky-Fadin-Kuraev-Lipatov (BFKL) approach is established...

53. Hadronic structure at a Forward Physics Facility

Dr Francesco Giovanni Celiberto (ECT*/FBK Trento & INFN-TIFPA)

Inclusive as well as exclusive forward emissions are widely recognized as excellent channels to access the nucleon structure in the high-energy/small-$x$ regime. Here, several phenomenological analyses have been proposed so far, this allowing us to probe kinematic ranges in the intersection corners of different approaches. At large transverse momenta, a high-energy factorization (HEF) formula...

92. Probing PDFs via Neutrino Scattering with FASER$\nu$

Jason Arakawa

28/05/2021, 17:30

We study the impact that FASER(\nu) will have on the determination of nuclear and nucleon PDFs using neutrino/anti-neutrino deep inelastic scattering $\nu_{\mu} q \rightarrow \mu^- q^{\prime}$. FASER$\nu$ will be able to probe a broader range of the $x, y,$ and $Q^2$ parameter space with the access to the high energy neutrinos generated from interactions at ATLAS. For the nucleon PDFs focus...

51. LEvEL: Low-Energy Neutrino Experiment at the LHC

Kevin Kelly (Fermilab)

28/05/2021, 17:45

The Large Hadron Collider Beam Dump, where an enormous number of 7 TeV protons are brought to rest twice a day, is an intense source of neutrinos. In this talk, I will discuss a proposed experimental program, LEvEL, the Low-Energy Neutrino Experiment at the LHC, which can measure several interesting neutrino-interaction cross sections near the LHC Beam Dump. These interaction processes may...

90. Addressing the cosmic ray muon excess by probing a "fireball" state at the Forward Physics Facility

Julien Manshanden

28/05/2021, 18:00

The muon excess in cosmic ray data can be traced back to uncertainties on the hadronic energy fraction after forward interactions. These uncertainties could be addressed by the Forward Physics Facility (FPF) if neutrino measurements will be able to constrain the charged pion to kaon ratio and the charm production in very forward interactions.
I will discuss a "fireball" model which increases...

52. Dark Sectors via Proton Bremsstrahlung

Saeid Foroughi-Abari (University of Victoria)

28/05/2021, 18:15

In this talk, I discuss the production of dark vectors and scalars via proton bremsstrahlung, making use of a model that accurately captures the underlying nucleon scattering cross-section in the forward direction due to pomeron exchange.
