During the run III of the LHC, the forward experiments FASER$\nu$ and SND@LHC will be able to detect the Charged Current (CC) interactions of the high energy neutrinos of all three flavors produced at the ATLAS Interaction Point (IP). This opportunity may unravel mysteries of the third generation leptons. We build three models that can lead to a tau excess at these detectors through the...

Light sub-GeV dark matter and dark sector particles can be copiously produced in the far forward direction at the LHC. The proposed FLArE, FASERnu2, and FASER2 experiments, housed in the Forward Physics Facility, can be sensitive to a variety of dark matter scattering and other associated dark sector signatures during the HL-LHC era. This talk will provide an overview of this possibility,...

Similar to millichagred particles, dark states with electromagnetic form factors can be probed at FLArE by scattering signals with SM particles in the detector. I will discuss details of production channels and the detection mechanism. Finally, I will present the projected sensitivity of FLArE.

Sterile neutrinos are hypothetical massive neutral leptons, which mix with the neutrinos of the Standard Model, and which are singlets of the SM gauge symmetry. Therefore their mass term can be included directly in the Lagrangian, assuming they are Majorana fermions. They are motivated by their potential to explain the origin of dark matter, light neutrino masses and oscillations, and baryonic...

The high-luminosity of neutrinos at FASERv and FASERv2 makes them excellent facilities for neutrino studies. In this talk, after briefly reviewing very interesting physics from the 4-fermion operators, I will then present sensitivities to them at FASERv and FASERv2 model independently in the EFT framework. Time permitting, the corresponding implications on specific phenomenologically...

We investigate the observed muon deficit in air-shower simulations when compared to ultrahigh-energy cosmic ray (UHECR) data. We assume that the enhancement of strangeness production in high-energy hadronic collisions reported by the ALICE Collaboration is the keystone to resolve the muon anomaly and study the concomitant $\pi \leftrightarrow K$ swap impact on the shower development. We...

We consider the nonminimal quartic inflation in a classically conformal $U(1)_X$ extended SM. We show that if the inflaton mass and its mixing angle with the SM Higgs field lie in a suitable range, the FASER experiment can search for the inflaton at the High Luminosity (HL)-LHC. Also because of the classical conformal invariance, the inflationary predictions and the LHC search for the $U(1)_X$...

Far-forward tau neutrinos and antineutrinos come predominantly from Ds± production in pp collisions, followed by the leptonic decay of these mesons. At such large pseudorapidities, theoretical predictions rely on parton distribution functions (PDFs) in a combination of very small and large parton−x values. We evaluate the 3-flavor PROSA PDF uncertainties in a next-to-leading order (NLO) QCD...

In the search for new physics, the dark photon is one of the most studied

targets. It is often invoked as a mediator connecting the SM to a secluded dark
sector charged under a novel dark $U(1)_X$ symmetry. However, beyond
the minimal secluded dark photon model there is a myriad of anomaly-free U(1)
extensions of the SM, which originate from gauging combinations the accidental

The event generator, Pythia, has been invaluable in making predictions at colliders like the LHC. However, Pythia was tuned with central ($\eta$<5) measurements, and so it should not be expected to reproduce forward physics data, such as what the LHCf collaboration has obtained ($\eta$>10). If new physics is to be probed at the proposed FPF, one must sufficiently understand the incoming shower...

We provide a robust calculation of hadronic decays of light vector particles ($m<2$ GeV) into an extensive set of final state configurations of mesons and baryons. We improve currently considered mesonic decay channels as included in DarkCast, and complement them by a large list of additional channels, especially in the range of excited $\rho$, $\omega$, and $\phi$ states above $m>1$ GeV. We...

There are no neutrino cross-section measurements from 400 GeV to 10 TeV. Nevertheless, experiments like FASERnu estimate interaction rates that will allow us to measure the cross section in this unexplored region. Neutrinos with energies above a few hundred GeV will primarily interact via Deep Inelastic Scattering. We compare different model predictions in this energy range.

We study a novel dark matter production mechanism based on the freeze-in through semi-production, i.e. the inverse semi-annihilation processes. A peculiar feature of this scenario is that the production rate is suppressed by a small initial abundance of dark matter and consequently creating the observed abundance requires much larger coupling values than for the usual freeze-in. We provide a...

Neutrino experiments of the FPF will be able to measure different types of neutrino interactions due to its broad energy range. In this talk, we discuss neutrino cross sections in the transition region between the shallow- and deep- inelastic scattering focusing on the impact of $W_{min}$ and $Q^2$.

In certain supersymmetric scenarios, no existing mass bounds apply to the lightest neutralino. In the case of broken R-parity, such very-light neutralinos — produced via rare decays of mesons — may decay radiatively over macroscopic timescales leading to a single boosted-photon signature in the far-forward region at the LHC. We consider various R-parity Violating Supersymmetry (RPV-SUSY)...

The searches of axion-like particles (ALP) are strongly motivated by the general dark sector, strong CP problem and axiom quality problem etc. We focus on the gluonic coupling to ALP which is relevant to the strong CP puzzle and is of great importance. We propose the axion as the bremsstrahlung radiation off the proton in the typical proton-proton collision which has not been incorporated in...

We discuss detection prospects for Standard Model resonances at FASER$\nu$ and FLArE. The primary channel of interest is the production of $\rho^-$ resonances which yield two-pion final states, $\pi^-\pi^0$, with no additional hadronic activity and no leptons in the final state. We conclude that FASER$\nu$ (and especially FASER$\nu$-2) have the best detection prospects due to their nuclear...

Light new physics has become a particularly active research direction, in particular with the proposed dedicated Forward Physics Facility at CERN, as well as with the upcoming FASER detector measurements. In the talk, we will describe how the small lifetime regime of light long-lived particles in the non-minimal BSM scenarios based on renormalizable portals can be covered in the FPF using the...
