Thresholds in Particle Physics [PDF]

, 1981
Experimentally, particle physics is more or less known to about 18 GeV, the present limit on the mass of the top quark. Theoretically everything seems well described by the standard model of strong, e.m. and weak interactions [l].

Minimal radiative neutrino masses

Journal of High Energy Physics, 2019
We conduct a systematic search for neutrino mass models which only radiatively produce the dimension-5 Weinberg operator. We thereby do not allow for additional symmetries beyond the Standard Model gauge symmetry and we restrict ourselves to minimal ...

Multi-spin soft bootstrap and scalar-vector Galileon

Journal of High Energy Physics, 2021
We use the amplitude soft bootstrap method to explore the space of effective field theories (EFT) of massless vectors and scalars. It is known that demanding vanishing soft limits fixes uniquely a special class of EFTs: non-linear sigma model, scalar ...

Octonions, E6, and Particle Physics

, 2010
In 1934, Jordan et al. gave a necessary algebraic condition, the Jordan identity, for a sensible theory of quantum mechanics. All but one of the algebras that satisfy this condition can be described by Hermitian matrices over the complexes or quaternions.

Dai-Freed anomalies in particle physics [PDF]

Journal of High Energy Physics, 2018
Anomalies can be elegantly analyzed by means of the Dai-Freed theorem. In this framework it is natural to consider a refinement of traditional anomaly cancellation conditions, which sometimes leads to nontrivial extra constraints in the fermion spectrum.

Tetraquarks at large M and large N

Journal of High Energy Physics
We study tetraquarks in large N QCD with heavy quarks, in the domain where non-relativistic quantum mechanics offers an adequate approximation. Within the regime of validity of the Born-Oppenheimer approximation, we systematically study and explicitly ...

Noncommutative Geometry and Particle Physics [PDF]

Proceedings of Corfu Summer Institute 2017 "Schools and Workshops on Elementary Particle Physics and Gravity" — PoS(CORFU2017), 2018
We review the noncommutative approach to the standard model. We start with the introduction if the mathematical concepts necessary for the definition of noncommutative spaces, and manifold in particular.

Two-loop amplitudes for processes gg → Hg, qg → Hq and qq¯→Hg $$ \mathrm{q}\overline{\mathrm{q}}\to \mathrm{H}\mathrm{g} $$ at large Higgs transverse momentum

Journal of High Energy Physics, 2018
We compute the two-loop QCD corrections to amplitudes for processes gg → Hg, qg → Hq and qq¯→Hg $$ q\overline{q}\to Hg $$ in the limit when the Higgs transverse momentum is larger than the top quark mass, p ⊥ ≫ m t .
