Sterile Neutrino Production Through a Matter Effect Enhancement at Long Baselines
Joseph Bramante
If sterile neutrinos have a neutral coupling to standard model fermions, matter effect resonant transitions to sterile neutrinos and excess neutral-current events could manifest at…
Large Jet Multiplicities and New Physics at the LHC
Joseph Bramante, Jason Kumar, Brooks Thomas
A broad class of scenarios for new physics involving additional strongly-interacting fields generically predicts signatures at hadron colliders which consist solely of large number…
Local Scale-Dependent Non-Gaussian Curvature Perturbations at Cubic Order
Joseph Bramante, Jason Kumar
We calculate non-Gaussianities in the bispectrum and trispectrum arising from the cubic term in the local expansion of the scalar curvature perturbation. We compute to three-loop o…
Collider Searches for Fermiophobic Gauge Bosons
Joseph Bramante, R. S. Hundi, Jason Kumar +2
We explore the phenomenology of an extra U(1) gauge boson which primarily couples to standard model gauge bosons. We classify all possible parity-odd couplings up to dimension 6 op…
