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...
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...
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...
