Flavorful Supersymmetry
Yasunori Nomura, Michele Papucci, Daniel Stolarski
Weak scale supersymmetry provides elegant solutions to many of the problems of the standard model, but it also generically gives rise to excessive flavor and CP violation. We show…
Possible complex annihilation and B -> K pi direct CP asymmetry
Junegone Chay, Hsiang-nan Li, Satoshi Mishima
We point out that a sizable strong phase could be generated from the penguin annihilation in the soft-collinear effective theory for B meson decays. Keeping a small scale suppresse…
Hypercharged Anomaly Mediation
Radovan Dermisek, Herman Verlinde, Lian-Tao Wang
We show that, in string models with the MSSM residing on D-branes, the bino mass can be generated in a geometrically separated hidden sector. Hypercharge mediation thus naturally t…
Massive Vector Scattering in Lee-Wick Gauge Theory
Benjamin Grinstein, Donal O'Connell, Mark B. Wise
We demonstrate that amplitudes describing scattering of longitudinally polarized massive vector bosons present in non-Abelian Lee-Wick gauge theory do not grow with energy and, hen…
Z'-mediated Supersymmetry Breaking
Paul Langacker, Gil Paz, Lian-Tao Wang +1
We consider a class of models in which supersymmetry breaking is communicated dominantly via a U'(1) gauge interaction, which also helps solve the μproblem. Such models can emerge…
Theory and Phenomenology of Exotic Isosinglet Quarks and Squarks
Junhai Kang, Paul Langacker, Brent D. Nelson
Extensions of the MSSM often predict the existence of new fermions and their scalar superpartners which are vectorlike with respect to the standard model gauge group but may be chi…
