B-decay anomalies in Pati-Salam SU(4)

Riccardo Barbieri, Andrea Tesi

Attempts to incorporate in a coherent picture the -decay anomalies presumably observed in and semi-leptonic decays have to face the absence of…

Dedicated Strategies for Triboson Signals from Cascade Decays of Vector Resonances

Kaustubh Agashe, Jack H. Collins, Peizhi Du +3

New colorless electroweak (EW) charged spin-1 particles with mass of a few TeV arise in numerous extensions of the Standard Model (SM). Decays of such a vector into a pair of SM pa…

A generic anti-QCD jet tagger

J. A. Aguilar-Saavedra, Jack H. Collins, Rashmish K. Mishra

New particles beyond the Standard Model might be produced with a very high boost, for instance if they result from the decay of a heavier particle. If the former decay hadronically…

Dark Matter as a weakly coupled Dark Baryon

Andrea Mitridate, Michele Redi, Juri Smirnov +1

Dark Matter might be an accidentally stable baryon of a new confining gauge interaction. We extend previous studies exploring the possibility that the DM is made of dark quarks hea…

Effective Theory of Flavor for Minimal Mirror Twin Higgs

Riccardo Barbieri, Lawrence J. Hall, Keisuke Harigaya

We consider two copies of the Standard Model, interchanged by an exact parity symmetry, P. The observed fermion mass hierarchy is described by suppression factors for cha…

Cosmological Implications of Dark Matter Bound States

Andrea Mitridate, Michele Redi, Juri Smirnov +1

We present generic formulae for computing how Sommerfeld corrections together with bound-state formation affects the thermal abundance of Dark Matter with non-abelian gauge interac…

Precision Tests and Fine Tuning in Twin Higgs Models

Roberto Contino, Davide Greco, Rakhi Mahbubani +2

We analyze the parametric structure of Twin Higgs (TH) theories and assess the gain in fine tuning which they enable compared to extensions of the Standard Model with colored top p…
