CP Violating Contribution to Delta Gamma in the B_s System from Mixing with a Hidden Pseudoscalar
Yang Bai, Ann E. Nelson
Recent evidence for a CP violating asymmetry in the semileptonic decays of B_s mesons cannot be accommodated within the Standard Model. Such an asymmetry can be explained by new ph…
A Light Dilaton in Walking Gauge Theories
Thomas Appelquist, Yang Bai
We analyze the existence of a dilaton in gauge theories with approximate infrared conformal symmetry. To the extent that these theories are governed in the infrared by an approxima…
The Tevatron at the Frontier of Dark Matter Direct Detection
Yang Bai, Patrick J. Fox, Roni Harnik
Direct detection of dark matter (DM) requires an interaction of dark matter particles with nucleons. The same interaction can lead to dark matter pair production at a hadron collid…
Topological Pions
Yang Bai, Adam Martin
We study the collider signatures of new pions, composite particles which emerge from a TeV-scale, confining gauge theory with vector-like matter. Similar to the neutral pion in QCD…
