Weakly-Coupled Higgs Bosons and Precision Electroweak Physics [PDF]
, 2003 We examine the prospects for discovering and elucidating the weakly-coupled Higgs sector at future collider experiments. The Higgs search consists of three phases: (i) discovery of a Higgs candidate, (ii) verification of the Higgs interpretation of the signal, and (iii) precision measurements of Higgs sector properties. The discovery of one Higgs boson

Journal of High Energy PhysicsTri-boson production together with vector-boson scattering is a privileged channel to study the electroweak structure of the Standard Model. Upcoming LHC running stages will allow to measure these processes at unprecedented accuracy and for all possible ...

Electroweak limits on physics beyond the Standard Mode
EPJ Web of Conferences, 2013 We briefly review the global Standard Model fit to electroweak precision data, and discuss the status of electroweak constraints on new interactions. We follow a general effective Lagrangian approach to obtain modelindependent limits on the dimension-six

THE TOP PRIORITY: PRECISION ELECTROWEAK PHYSICS FROM LOW TO HIGH ENERGY [PDF]
International Journal of Modern Physics A, 2004 Overall, the Standard Model describes electroweak precision data rather well. There are however a few areas of tension (charged current universality, NuTeV, (g-2)μ, b quark asymmetries), which I review critically, emphasizing recent theoretical and experimental progress.

Testing the neutrino content of the muon at muon colliders
Journal of High Energy PhysicsCollinear 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 ...

Electroweak corrections to Higgs+jet production in gluon fusion
Journal of High Energy PhysicsWe 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 ...

Electroweak splitting functions in the Standard Model and beyond
Journal of High Energy PhysicsWe 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 ...

Parity violation in Møller scattering within low-energy effective field theory
Journal of High Energy PhysicsWe include electroweak effects in Møller scattering at low energies in an effective field theory approach and compute the left-right parity-violating asymmetry.

Electron-positron annihilation into heavy leptons at two loops
Journal of High Energy PhysicsWe calculate the NNLO QED corrections to the C-even part of differential cross section of e + e − → μ + μ − process. We neglect power corrections in the electron mass and obtain the result in terms of Goncharov’s polylogarithms.

Mixed QCD-EW corrections to W-pair production at electron-positron colliders
Journal of High Energy PhysicsThe discrepancy between the CDF measurement and the Standard Model theoretical prediction for the W-boson mass underscores the importance of conducting high-precision studies on the W boson, which is one of the predominant objectives of proposed future e
