Minimal cascade decay of the top quark through a new scalar
Bogdan A. Dobrescu, Max H. Fieg, Alessandro Russo
We explore a possible decay of the top quark into a new scalar plus a charm quark. The decay is mediated by a dimension-5 operator that may be generated by the exchange of a…
The X17 with Chiral Couplings
Max H. Fieg, Toni Mäkelä, Tim M. P. Tait +1
In recent years, the ATOMKI collaboration has performed a series of measurements of excited nuclei, observing a resonant excess of electron-positron pairs at large opening angles c…
Octet scalars shaping LHC distributions in 4-jet final states
Bogdan A. Dobrescu, Max H. Fieg
We study properties of a hypothetical scalar particle, , which is a color octet and an electroweak singlet. At hadron colliders, is pair produced through its QCD coupling to…
The LHC as a TeV Muon Beam Dump: Muonphilic Scalars at FASER
Roshan Mammen Abraham, Max Fieg
The FASER experiment was designed to study long-lived dark sector particles and neutrinos traveling in the forward direction at the LHC. Neutrinos are predominantly produced from m…
FPF@FCC: Neutrino, QCD, and BSM Physics Opportunities with Far-Forward Experiments at a 100 TeV Proton Collider
Roshan Mammen Abraham, Jyotismita Adhikary, Jonathan L. Feng +7
Proton-proton collisions at energy-frontier facilities produce an intense flux of high-energy light particles, including neutrinos, in the forward direction. At the LHC, these part…
New Physics in Single Resonant Top Quarks
Shelley Tong, James Corcoran, Max Fieg +2
Searches for new physics in the top quark sector are of great theoretical interest, yet some powerful avenues for discovery remain unexplored. We characterize the expected statisti…
Tuning Pythia for Forward Physics Experiments
Max Fieg, Felix Kling, Holger Schulz +1
Event generators like Pythia play an important role in physics studies at the Large Hadron Collider (LHC). While they make accurate predictions in the central region, i.e. at pseud…
The LHC as a Neutrino-Ion Collider
Juan M. Cruz-Martinez, Max Fieg, Tommaso Giani +4
Proton-proton collisions at the LHC generate a high-intensity collimated beam of neutrinos in the forward (beam) direction, characterised by energies of up to several TeV. The rece…
Extending the Discovery Potential for Inelastic-Dipole Dark Matter with FASER
Keith R. Dienes, Jonathan L. Feng, Max Fieg +3
Neutral particles are notoriously difficult to observe through electromagnetic interactions. As a result, they naturally elude detection in most collider detectors. In this paper,…
Hadrophilic Dark Sectors at the Forward Physics Facility
Brian Batell, Jonathan L. Feng, Max Fieg +4
Models with light dark sector and dark matter particles motivate qualitatively new collider searches. Here we carry out a comprehensive study of hadrophilic models with U(1) an…
The Forward Physics Facility: Sites, Experiments, and Physics Potential
Luis A. Anchordoqui, Akitaka Ariga, Tomoko Ariga +78
The Forward Physics Facility (FPF) is a proposal to create a cavern with the space and infrastructure to support a suite of far-forward experiments at the Large Hadron Collider dur…
