Accurate prediction of electroweak observables and impact on the Higgs mass bound [PDF]
, 1998 I discuss the importance of the $O(g^4 m_t^2/\mw^2)$ corrections to the effective electroweak angle and Mw in the indirect determination of the Higgs mass. I emphasize the r\^ole of a very precise Mw measurement on the Mh estimate.Comment: 9 pages, LaTex,

Neutrinoproduction of Photons and Pions From Nucleons in a Chiral Effective Field Theory for Nuclei
, 2012 Neutrino-induced productions (neutrinoproduction) of photons and pions from nucleons and nuclei are important for the interpretation of neutrino-oscillation experiments, as they are potential backgrounds in the MiniBooNE experiment [A. A. Aquilar-Arevalo

Annalen der Physik, Volume 536, Issue 1, January 2024.A primer on axion physics, emphasizing an intuitive understanding of why the axion solves the strong CP problem. Abstract The canonical axion potential is reviewed, with an emphasis on the field theory underlying radial and angular modes of complex scalar fields.

Double neutral-current corrections to NLO electroweak leptonic cross sections
Journal of High Energy PhysicsWe present a method for improving next-to-leading order electroweak (EW) predictions for lepton-scattering processes by consistently including double neutral-current corrections arising from vector-boson-fusion topologies, which are formally of higher ...

Higgs boson contribution to the leading two-loop Yukawa corrections to gg → HH
Journal of High Energy Physics, 2022 We analytically compute two-loop Yukawa corrections to Higgs boson pair production in the high-energy limit. Such corrections are generated by an exchange of a Higgs boson between the virtual top quark lines.

Evaluation of the Theoretical Uncertainties in the Z to ll Cross Sections at the LHC
, 2008 We study the sources of systematic errors in the measurement of the Z to ll cross-sections at the LHC. We consider the systematic errors in both the total cross-section and acceptance for anticipated experimental cuts.

Higgs‐induced screening mechanisms in scalar‐tensor theories
Annals of the New York Academy of Sciences, Volume 1531, Issue 1, Page 95-103, January 2024.Abstract We consider the theory of a light conformally coupled scalar field, that is, one that is coupled directly to the Ricci scalar of the gravitational sector. This theory can be written equivalently as one of a light scalar that is coupled to the Standard Model of particle physics with a particular combination of Higgs‐portal couplings.

Journal of High Energy PhysicsWe present automated next-to-leading order QCD and/or electroweak (EW) predictions for photon-photon processes in ultraperipheral high-energy collisions of protons and ions, extending the capabilities of the MadGraph5_aMC@NLO framework together in ...

Strongly Interacting Dynamics beyond the Standard Model on a Spacetime Lattice
, 2010 Strong theoretical arguments suggest that the Higgs sector of the Standard Model of the Electroweak interactions is an effective low-energy theory, with a more fundamental theory that is expected to emerge at an energy scale of the order of the TeV.
