TL;DR: In this article, a spherically symmetric monopole and dyon solution with magnetic charge 4π e in the standard Weinberg-Salam model was presented, which could be interpreted as a non-trivial hybrid between the abelian Dirac and non-abelian 't Hooft-Polyakov monopole with an electric charge.

TL;DR: In this article, it was shown that the most important quantum effects are the modifications of the leptonic couplings of the W and Z vector bosons and the generation of a purely lepton effective Lagrangian.
Abstract: The growing experimental indication of Lepton Flavour Universality Violation (LFUV) both in charged- and neutral-current semileptonic B-decays, has triggered many theoretical interpretations of such non-standard phenomena. Focusing on popular scenarios where the explanation of these anomalies requires New Physics at the TeV scale, we emphasise the importance of including electroweak corrections to obtain trustable predictions for the models in question. We find that the most important quantum effects are the modifications of the leptonic couplings of the W and Z vector bosons and the generation of a purely leptonic effective Lagrangian. Although our results do not provide an inescapable no-go theorem for the explanation of the B anomalies, the tight experimental bounds on Z-pole observables and τ decays challenge an explanation of the current non-standard data. We illustrate how these effects arise, by providing a detailed discussion of the running and matching procedure which is necessary to derive the low-energy effective Lagrangian.

TL;DR: In this article, a model-independent approach based on a general effective Lagrangian was proposed to analyze the interplay between SUSY breaking and electroweak breaking, generalizing earlier results.

TL;DR: In this article, a phenomenological application of the joint resummation formalism to electroweak annihilation processes at a measured boson momentum was presented, which simultaneously resums at next-to-leading logarithmic accuracy with large threshold and recoil corrections to partonic scattering.
Abstract: We present a phenomenological application of the joint resummation formalism to electroweak annihilation processes at a measured boson momentum ${Q}_{T}$ This formalism simultaneously resums at next-to-leading logarithmic accuracy large threshold and recoil corrections to partonic scattering We invert the impact parameter transform using a previously described analytic continuation procedure This leads to a well-defined, resummed perturbative cross section for all nonzero ${Q}_{T},$ which can be compared to resummation carried out directly in ${Q}_{T}$ space From the structure of the resummed expressions, we also determine the form of nonperturbative corrections to the cross section and implement these into our analysis We obtain a good description of the transverse momentum distribution of Z bosons produced at the Fermilab Tevatron collider

TL;DR: In this paper, the chargino-mediated baryogenesis in the Minimal Supersymmetric Standard Model (MSMS) was investigated. But the authors only considered the chargin-mediated Baryogenesis with respect to the top sector of the SSMs.
