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.

Fermion-Fermion Gluing by Means of Unobservable Scalar Bosons

open access: yes, 2002
A theory of several fermion fields interacting with several scalar fields is suggested. The model is nonlocal and is partially solvable under arbitrary choice of its formfactors. The latter are shown to determine the resulting fermion-fermion interaction.

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.

Four-Fermion Dynamics and Fermion Masses [PDF]

open access: yesProgress of Theoretical Physics Supplement, 1996
Four-fermion operators with large anomalous dimension may feed down mass to quarks and leptons from a heavy fourth family. No technicolor sector is required. A model illustrates the origin of the large top mass along with quark mass hierarchies and mass mixings.

Pairing in two-dimensional boson-fermion mixtures [PDF]

open access: yes, 2004
The possibilities of pairing in two-dimensional boson-fermion mixtures are carefully analyzed. It is shown that the boson-induced attraction between two identical fermions dominates the p wave pairing at low density.

A Fermion Primer

open access: yes
This is a review paper intended to illustrate a few critical issues concerning Dirac, Weyl and Majorana fermions and their differences. The first part consists in basic introductions to fermions, and more in detail to fermions in 4d, focusing in particular in what differentiate the three type of fermions: chirality, helicity, mass, field equations ...

The fermion-fermion effective potential in the maxwell-chern-simons theory [PDF]

open access: yes, 1992
The effective nonrelativistic potential VT describing the fermion-fermion interaction in the Maxwell-Chern-Simons theory is derived to the lowest order in perturbation theory.

Fermion parity resolution of entanglement

open access: yesJournal of High Energy Physics
Entanglement is analyzed in the Majorana fermion conformal field theory (CFT) in the vacuum, in the fermion state, and in states built from conformal interfaces.

Discrete Chyrality and Fermion Zero Modes

open access: yes, 1983
In a quantum 1 + 1 dimensional fermion-soliton system the boson condensation in terms of which the soliton solution can be described affects the fermionic structure behaviour due to the soliton non-trivial topology.
