Testing the neutrino content of the muon at muon colliders

Journal of High Energy Physics
Collinear emission of W bosons off a high-energy muon induces a large muon-neutrino component among the Parton Distribution Functions (PDFs) of a muon. In this paper we study the phenomenology related to the ν μ PDF at future high-energy muon colliders ...

Theoretical uncertainties for measurements of alpha_s from electroweak observables

, 2005
One of the most precise measurements of the strong coupling constant alpha_s(MZ) is obtained in the context of global analyses of precision electroweak data.

Electroweak corrections to Higgs+jet production in gluon fusion

Journal of High Energy Physics
We present the calculation of complete next-to-leading order electroweak corrections to the Higgs boson production in gg → gH channel. We apply the method of differential equations combined with the selection of optimized master integrals to accomplish ...

Measuring the W Boson Mass at Hadron Colliders [PDF]

, 2003
We discuss the prospects for measuring the W mass in Run II of the Tevatron and at the LHC. The basic techniques used to measure M_W are described and the statistical, theoretical and detector-related uncertainties are discussed in detail.Comment: Latex,

Towards the Theory of Cosmological Phase Transitions

, 1992
We discuss recent progress (and controversies) in the theory of finite temperature phase transitions. This includes the structure of the effective potential at a finite temperature, the infrared problem in quantum statistics of gauge fields, the theory ...

Electroweak splitting functions in the Standard Model and beyond

Journal of High Energy Physics
We derive quasi-collinear factorization formulas in generic spontaneously broken gauge theories with scalars, fermions, and vector bosons. Specifically, we obtain polarized leading-order splitting functions for all possible final-state and initial-state ...

Two-loop running effects in Higgs physics in Standard Model Effective Field Theory

Journal of High Energy Physics
We consider the renormalization group equations within the Standard Model Effective Field Theory and compute two-loop contributions proportional to the top quark Yukawa coupling for the operator generating an effective Higgs-gluon coupling, focusing on ...

Electroweak corrections in the SMEFT: four-fermion operators at high energies

Journal of High Energy Physics
In the Standard Model (SM), electroweak (EW) corrections become significant at high energies, particularly at the tera-electronvolt scale and beyond, due to the presence of Sudakov logarithms.

Stabilizing the electroweak vacuum by higher dimensional operators in a Higgs-Yukawa model

, 2013
The Higgs boson discovery at the LHC with a mass of approximately 126 GeV suggests, that the electroweak vacuum of the standard model may be metastable at very high energies. However, any new physics beyond the standard model can change this picture.

Electroweak corrections to hadronic event shapes

, 2010
We report on a recent calculation of the electroweak O(\alpha^3\alpha_s) corrections to 3-jet production and related event-shape observables at e+e- colliders.
