The One-Loop Correction to Heavy Dark Matter Annihilation
Grigory Ovanesyan, Nicholas L. Rodd, Tracy R. Slatyer +1
We calculate the one-loop corrections to TeV scale dark matter annihilation in a model where the dark matter is described by an SU(2) triplet of Majorana fermions, such as the…
Dark Gauge Bosons: LHC Signatures of Non-Abelian Kinetic Mixing
Carlos A. Argüelles, Xiao-Gang He, Grigory Ovanesyan +2
We consider non-abelian kinetic mixing between the Standard Model SU(2 and a dark sector U(1 gauge group associated with the presence of a scalar SU(2 triplet.…
Initial-state splitting kernels in cold nuclear matter
Grigory Ovanesyan, Felix Ringer, Ivan Vitev
We derive medium-induced splitting kernels for energetic partons that undergo interactions in dense QCD matter before a hard-scattering event at large momentum transfer . Work…
Jet Quenching from QCD Evolution
Yang-Ting Chien, Alexander Emerman, Zhong-Bo Kang +2
Recent advances in soft-collinear effective theory with Glauber gluons have led to the development of a new method that gives a unified description of inclusive hadron production i…
Two-Step Electroweak Baryogenesis
Satoru Inoue, Grigory Ovanesyan, Michael J. Ramsey-Musolf
We analyze electroweak baryogenesis during a two-step electroweak symmetry breaking transition, wherein the baryon asymmetry is generated during the first step and preserved during…
Jet quenching beyond the energy loss approach
Grigory Ovanesyan
We study the jet quenching effect in heavy ion collisions, based on medium-induced splitting functions calculated from Soft Collinear Effective Theory with Glauber Gluons. Our meth…
