Observables in quantum field theory on a collapsing black hole background

Micheal S. Berger, Zhi Liu

We study the quantum radiation from a curved background using scalar observables constructed from the (1+1) dimensional renormalized stress-energy tensor (RSET). We compute energy…

A Froggatt-Nielsen flavor model for neutrino physics

Micheal S. Berger, Maria Dawid

Superheavy neutrinos can, via the seesaw model, provide a mechanism for lepton number violation. If they are combined with flavor violation as characterized by the Froggatt-Nielsen…

Lorentz and CPT Violation in Heavy Quark Physics

M. S. Berger

Violations of the Lorentz and CPT symmetries can appear as observable effects in the direct production of top quarks and their subsequent decays. Earlier results for the …

Lorentz and CPT Violation in Top-Quark Production

Zhi Liu

Signals for Lorentz and CPT violation can appear in a wide range of experiments including hadron colliders like the LHC. We present a calculation of the Lorentz-violating cross sec…

Lorentz and CPT Violation in Top-Quark Production and Decay

Micheal S. Berger, Alan Kostelecky, Zhi Liu

The prospects are explored for testing Lorentz and CPT symmetry in the top-quark sector. We present the relevant Lagrange density, discuss physical observables, and describe the si…

Lorentz Violation in Top-Quark Physics

M. S. Berger

Lorentz and CPT violation can affect the rates for -$\ol t$ production and decay. The Lorentz-violating coefficients in the Standard-Model Extension responsible for modifying th…
