Measurements of CP-conserving trilinear gauge boson couplings WWV (V≡γ,Z) in e+e− collisions at LEP2 [PDF]

open access: yes, 2009
The data taken by Delphi at centre-of-mass energies between 189 and 209 GeV are used to place limits on the CP-conserving trilinear gauge boson couplings , λ γ and Δκ γ associated to W + W − and single W production at Lep2.

Nonperturbative definition of the standard models

open access: yesPhysical Review Research, 2020
The standard models contain chiral fermions coupled to gauge theories. It has been a longstanding problem to give such gauged chiral fermion theories a quantum nonperturbative definition.

Phases and dynamics of few fermionic impurities immersed in two-dimensional boson droplets

open access: yesPhysical Review Research
We unravel the ground state properties and emergent nonequilibrium dynamics of a mixture consisting of a few spin-polarized fermions embedded in a two-dimensional bosonic quantum droplet. For an increasingly attractive droplet-fermion interaction we find

A complex singlet extension of the Standard Model with a singlet fermion dark matter

open access: yesNuclear Physics B
We examine a complex singlet scalar extension of the Standard Model (CxSM) with an extra singlet fermion. Both the singlet scalar and fermion are dark matter (DM) candidates.

Wilson Fermions with Four Fermion Interactions [PDF]

open access: yes, 2015
Four fermion interactions appear in many models of Beyond Standard Model physics. In Technicolour and composite Higgs models Standard Model fermion masses can be generated by four fermion terms.

Causal Fermion Systems and Octonions [PDF]

open access: yes
We compare the structures and methods in the theory of causal fermion systems with approaches to fundamental physics based on division algebras, in particular the octonions. We find that octonions and, more generally, tensor products of division algebras

Constraints on dark matter annihilation to fermions and a photon

open access: yesJournal of High Energy Physics, 2018
We consider Majorana dark matter annihilation to fermion-anti-fermion pair and a photon in the effective field theory paradigm, by introducing dimension 6 and dimension 8 operators in the Lagrangian.

Optimal Hamiltonian for Fermion flows [PDF]

open access: yes, 2006
We consider the problem of determining the noise coefficients of the Hamiltonian associated with a Fermion flow so as to minimize a naturally associated quadratic performance functional.
