An Operator Analysis of Radiative Muon Decay

Arvind Rajaraman, Chao-Hsiang Sheu

New physics beyond the Standard Model (SM) may induce new four-fermion interactions. We investigate the sensitivity of radiative muon decay, , to such four-f…

A Model of Annihilogenesis

Arvind Rajaraman, Alexander Stewart, Tim M. P. Tait

We present an explicit model of leptogenesis via annihilogenesis in which two right-handed Majorana neutrinos couple to the Standard Model lepton doublets and Higgs, and acquire a…

Probing Muon at a Future Muon Collider

Jason Arakawa, Arvind Rajaraman, Taotao Sui +1

The discrepancy in the of the muon provides a hint that may indicate that physics beyond the standard model is at play. A multi-TeV scale muon collider provides a na…

Indirect Detection of Low-mass Dark Matter Through the and Windows

J. G. Christy, Jason Kumar, Arvind Rajaraman

We consider the search for gamma-rays produced by the annihilation or decay of low-mass dark matter which couples to quarks. In this scenario, most of the photons are produced from…

Annihilogenesis

Jason Arakawa, Arvind Rajaraman, Tim M. P. Tait

We investigate a novel interplay between the decay and annihilation of a particle whose mass undergoes a large shift during a first order phase transition, leading to the particles…

How to produce antinuclei from dark matter

Julian Heeck, Arvind Rajaraman

We show how to produce antideuteron, antihelium, and other antinuclei in large fractions from the decays of a new particle that carries baryon number. Close to threshold, the p…
