Spurious Poles in the Scattering of Electric and Magnetic Charges
John Terning, Christopher B. Verhaaren
Theories with both electric and magnetic charges ("mutually non-local" theories) have several major obstacles to calculating scattering amplitudes. Even when the interaction arises…
Understanding Q-Balls Beyond the Thin-Wall Limit
Julian Heeck, Arvind Rajaraman, Rebecca Riley +1
Complex scalar fields charged under a global U(1) symmetry can admit non-topological soliton configurations called Q-balls which are stable against decay into individual particles…
Dynamical Evidence For a Fifth Force Explanation of the ATOMKI Nuclear Anomalies
Jonathan L. Feng, Tim M. P. Tait, Christopher B. Verhaaren
Recent anomalies in Be and He nuclear decays can be explained by postulating a fifth force mediated by a new boson . The distributions of both transitions are consistent…
Breaking Mirror Twin Color
Brian Batell, Wei Hu, Christopher B. Verhaaren
We investigate simple extensions of the Mirror Twin Higgs model in which the twin color gauge symmetry and the discrete mirror symmetry are spontaneously broken. This is acco…
A Minimal Model for Neutral Naturalness and pseudo-Nambu-Goldstone Dark Matter
Aqeel Ahmed, Saereh Najjari, Christopher B. Verhaaren
We outline a scenario where both the Higgs and a complex scalar dark matter candidate arise as the pseudo-Nambu-Goldstone bosons of breaking a global symmetry to . T…
