Odd Decays from Even Anomalies: Gauge Mediation Signatures Without SUSY

We analyze the theory and phenomenology of anomalous global chiral symmetries in the presence of an extra dimension. We propose a simple extension of the Standard Model in 5D whose signatures closely resemble those of supersymmetry with gauge mediation, and we suggest a novel scalar dark matter candidate. ar X iv :0 90 1. 29 33 v1 [ he pph ] 1 9 Ja n 20 09

We point out that the decay mode D 0 → K 0 ¯ K 0 has no factorizable contribution. In the chiral perturbation language, treating D 0 as heavy, the O(p) contribution is zero. We calculate the nonfactorizable chiral loop contributions of order O(p 3). Then, we use a heavy-light type chiral quark model to calculate nonfactorizable tree level terms, also of order O(p 3), proportional to the gluon c...

(non)decoupling of mirror fermions

We study ’t Hooft anomaly matching in lattice models with strong Yukawa or multi-fermion interactions. Strong non-gauge interactions among the mirror fermions in a vectorlike lattice gauge theory are introduced with the aim to obtain, in a strong-coupling symmetric phase, a long-distance unbroken gauge theory with chiral fermions in a complex representation. We show how to use exact lattice chi...

As a non-perturbative and gauge invariant regularization the lattice provides a tool for deeper understanding of the celebrated Yang-Mills theory, QCD and chiral gauge theories. For illustration, I discuss some analytic developments on the lattice related to chiral symmetry, chiral fermions and improvement programs. Chiral symmetry on the lattice has an amazing history, and it might influence o...
