Electroweak Baryogenesis in the MSSM
, 1999 We review the baryogenesis scenario in the MSSM at the perturbative level and, in particular, the impact of two-loop corrections on the strength of the phase transition and the amount of generated baryon asymmetry.

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 ...

Two-loop light-quark Electroweak corrections to Higgs boson pair production in gluon fusion
Journal of High Energy PhysicsWe compute two-loop electroweak corrections to double Higgs boson production in gluon fusion mediated by light quarks in a fully analytical way. We determine a basis of master integrals satisfying canonical differential equations in dlog form, enhanced ...

Semileptonic decays of the Higgs boson at the Tevatron
, 2011 We examine the prospects for extending the Tevatron reach for a Standard Model Higgs boson by including the semileptonic Higgs boson decays h --> WW --> l nu jj for M_h >~ 2 M_W, and h --> W jj --> l nu jj for M_h

Quantum entanglement is quantum: ZZ production at the LHC
Journal of High Energy PhysicsPolarization and spin correlations in diboson systems serve as powerful tools for precision tests and searches for new physics. Recently, interpreting these observables through the lens of quantum information, for instance by examining whether the ...

Electroweak corrections in the SMEFT: four-fermion operators at high energies
Journal of High Energy PhysicsIn 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.

Corrections of Order $\alpha \alpha_s$ to W Boson Decays
, 2013 We present the calculation of the mixed two-loop QCD/electroweak corrections to hadronic W boson decays within the Standard Model. The optical theorem is applied to the W boson two-point function.

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

EVAluation of the Equivalent Vector boson Approximation at highest energy colliders
Journal of High Energy PhysicsCollider processes at the highest available partonic center-of-mass energies — 10 TeV and above — exhibit a new regime of electroweak interactions where electroweak gauge bosons mostly act as quasi-massless partons in vector boson fusion processes.
