Based on a broad selection of existing predictions to cover the phase space as well as possible, we investigate the highest achievable precision for the neutrino spectra expected at the FPF. The spectra are presented as a function of neutrino energy and the spatial radius of the interaction vertex, separately for each outgoing charged lepton flavor, thus demonstrating the increase in precision...

Many Dark Sector models contain photon-coupled long-lived particles. An outstanding example is an axion-like particle decaying into two photons. The forward physics detectors at the LHC, e.g., FASER, were shown to be particularly suitable for hunting ~sub-GeV ALPs thanks to numerous photons produced in pp collisions, which in turn are efficiently converted into ALPs by the Primakoff...

FASER, the ForwArd Search ExpeRiment, is a currently

operating experiment at the Large Hadron Collider (LHC) that can
detect light long-lived particles produced in the forward region of
the LHC interacting point. In this talk, we show the prospect of
detecting light CP-even and CP-odd scalars at FASER and FASER 2.
Considering a model-independent framework describing the most... -

I will discuss constraints imposed by swampland conjectures on neutrino masses and mixing, focussing attention on the region of the parameter space to be probed by FPF experiments.

The currently operating FASER experiment and the planned Forward Physics Facility (FPF) will detect a large number of neutrinos produced in proton-proton collisions at the LHC. In addition to neutrinos from pion and kaon decays, a significant contribution is expected from the decay of charmed hadrons, particularly for electron and tau neutrino flavors. In this talk, we shall discuss two QCD...

Quirks are a generic prediction of strongly-interacting hidden sectors with low Lambda. Such particles can be produced in large numbers at the LHC with high initial pT, but since they are tied together by a color string, the quirk--anti-quirk system has vanishing total pT and so propagates down the beam pipe into forward detectors. We show that quirks produce a spectacular signature of two...

The heavy-flavor production at the hadron collider provides an important venue to test our understanding of the strong interaction. Due to the large heavy-flavor mass, this process is perturbatively calculable in quantum chromodynamics. In this work, we apply our recently developed Simplified-ACOT scheme with massive phase space (S-ACOT-MPS) to the D-meson production, which can be directly...

We study the relevance of Initial- and Final-State radiation in QCD processes at the LHC as a production mechanism for dark photons. We implement dark photon splitting functions to quarks into the Monte-Carlo Generator Herwig and add it to the forward and backward evolution of the parton shower in LHC events. We simulate the most relevant forward physics processes, and identify in which way...

Proton beams at high luminosity colliders and fixed-target facilities offer remarkable sensitivity to new light weakly coupled degrees of freedom in the dark sector. In a recent study, we revisited the production of dark photons and dark scalars via proton bremsstrahlung for a range of beam energies, including those relevant to the proposed Forward Physics Facility (FPF) at the High Luminosity...

As the lightest of the heavy flavors, the charm quark occupies a liminal space in QCD, transgressing the boundary separating perturbative and nonperturbative dynamics. Charm thus plays a central role in efforts to refine QCD and our corresponding understanding of proton structure for experiments at the LHC and elsewhere. We outline a stubborn problem in the theory of nucleon structure: the...

The idea that new physics could take the form of feebly interacting particles (FIPs) — particles with a mass below the electroweak scale, but which may have evaded detection due to their tiny couplings or very long lifetime — has recently gained a lot of traction. A wide variety of experiments have been proposed to search for this type of particles. However, the assumptions made about the...

Event generators have largely been used for central physics predictions at the LHC and parameters regarding hadron production in these generators have been tuned using central physics data. In particular, Pythia has proven to be a reliable generator for central measurements, but it's prediction for forward particle production shows disagreement with LHCf data, which points to a need for a...

The recent observation of collider neutrinos by the FASER collaboration highlights the potential the forward direction at the LHC has for neutrino physics. In the HL-LHC era, we expect a significant number of neutrinos of all flavors in the forward direction, opening the way for precision studies using collider neutrinos at the proposed Forward Physics Facility (FPF). In this talk, I will...

We demonstrate that the searches for dark sector particles can provide probes of reheating scenarios, focusing on the Cosmic Millicharge Background (CmB) produced in the early universe. We discuss two scenarios of millicharge particles (mCPs), with or without kinetic mixing, as they have different theoretical motivations and cosmological signatures. The mCP without an accompanying dark photon...
