Yukawa theory in non-perturbative regimes: towards confinement, exact -function and conformal phase
Marco Frasca, Anish Ghoshal
We study possible hints towards confinement in a Z-invariant Yukawa system with massless fermions and a real scalar field in the strongly-coupled regime. Using the tools develo…
Flavor Violating Di- Higgs Coupling
Fayez Abu-Ajamieh, Marco Frasca, Sudhir K. Vempati
Di-Higgs couplings to fermions of the form are absent in the Standard Model, however, they are present in several physics Beyond Standard Model (BSM) extension…
Renormalisable Non-local Quark-Gluon Interaction: Mass Gap, Chiral Symmetry Breaking & Scale Invariance
Arpan Chatterjee, Marco Frasca, Anish Ghoshal +1
We derive a Nambu--Jona-Lasinio (NJL) model from a non-local gauge theory and show that it has confining properties at low energies. In particular, we present an extended approach…
Effective potential in non-perturbative gauge theories
Gianluca Calcagni, Marco Frasca, Anish Ghoshal
We consider a formalism to describe the false-vacuum decay of a scalar field in gauge theories in non-perturbative regimes. We find that the larger the gauge coupling with respect…
Quark confinement in QCD in the 't Hooft limit
Marco Frasca, Anish Ghoshal, Stefan Groote
We treat quantum chromodynamics (QCD) using a set of Dyson-Schwinger equations derived, in differential form, with the Bender-Milton-Savage technique. In this way, we are able to d…
Confining complex ghost degrees of freedom
Marco Frasca, Anish Ghoshal, Alexey S. Koshelev
We show a theorem proving that a non-local bosonic field upon a covariant interaction with a confining gauge field undergoes the confinement of its degrees of freedom present in th…
