The importance of flavor in SMEFT Electroweak Precision Fits

Journal of High Energy Physics, 2023
Effective field theory tools are essential for exploring non-Standard Model physics at the LHC in the absence of the discovery of new light particles.

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

Primer on Axion Physics

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.

Angular phase-space integrals with four denominators through Mellin-Barnes

Journal of High Energy Physics
We compute four-denominator angular phase-space integrals using the Mellin-Barnes (MB) technique in dimensional regularisation. Independent of the scattering process, an angular integral can be categorised based on the nature of the momenta appearing in ...

Theoretical Uncertainties in Electroweak Boson Production Cross Sections at 7, 10, and 14 TeV at the LHC

, 2010
We present an updated study of the systematic errors in the measurements of the electroweak boson cross-sections at the LHC for various experimental cuts for a center of mass energy of 7, 10 and 14 TeV.

Top-quark couplings to TeV resonances at future lepton colliders [PDF]

, 2000
We study the processes $W_L W_L \to t \bar t$ and $W_L Z_L \to t\bar b (\bar t b)$ at future lepton colliders as probes of the couplings of the top quark to resonances at the TeV scale.

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.

Top Quark Flavor Changing Couplings at a Muon Collider

Advances in High Energy Physics, Volume 2024, Issue 1, 2024.
There is growing interest in the development of a muon collider that would make it possible to produce lepton collisions at energies of several TeV. Among others, there can be significant contributions to electroweak gauge boson, Higgs boson, and top quark physics.
