TL;DR: In this paper, the authors examined various scenarios in which the Standard Model is extended by a light leptoquark state to solve for one or both B-physics anomalies, viz.

TL;DR: In this paper, a simple fermionic extension of the Standard Model involving one doublet and two singlet vector-like leptons was considered and the authors showed how such a simple scenario can give rise to a nontrivial thermal history of the Universe, involving strongly first order multistep phase transitions occurring at temperatures close to the electroweak scale.

TL;DR: In this article, a general effective Lagrangian for lepton flavor violation (LFV) in quark-lepton transitions is derived from the high-mass tails of the dilepton processes, which can be applied to generic new physics scenarios, including the ones with scalar, vector and tensor effective operators.

TL;DR: In this article, the fermionic universal one-loop effective action obtained by integrating out heavy vector-like fermions at one loop using functional techniques was presented, and the results were applied to integrate out the vector-and fermion-like Fermions appearing in a toy model and in a Fermionic model that exhibits strong cosmological phase transitions.
