Bosons after Symmetry Breaking in Quantum Field Theory

We present a unified description of the spontaneous symmetry breaking and its associated bosons in fermion field theory. There is no Goldstone boson in the fermion field theory models of Nambu-Jona-Lasinio, Thirring and QCD2 after the chiral symmetry is spontaneously broken in the new vacuum. The defect of the Goldstone theorem is clarified, and the ”massless boson” predicted by the theorem is ...

Effects of thermal diffusion and chemical reaction on MHD transient free convection flow past a porous vertical plate with radiation, temperature gradient dependent heat source in slip flow regime

An analytical investigation is conducted to study the unsteady free convection heat and mass transfer flow through a non-homogeneous porous medium with variable permeability bounded by an infinite porous vertical plate in slip flow regime while taking into account the thermal radiation, chemical reaction, the Soret number, and temperature gradient dependent heat source. The flow is considered u...

Dynamical Generation of Fermion Mass and Magnetic Field in Three-Dimensional QED with Chern-Simons Term

We study dynamical symmetry breaking in three-dimensional QED with a Chern-Simons (CS) term, considering the screening effect ofN flavor fermions. We find a new phase of the vacuum, in which both the fermion mass and a magnetic field are dynamically generated, when the coefficient of the CS term κ equals Ne/4π. The resultant vacuum becomes the finite-density state halffilled by fermions. For κ ...

Traumatic Supratrochlear Artery Pseudoaneurysm With Spontaneous Resolution

Background: Traumatic pseudoaneurysm of the supratrochlear artery is a rare lesion. It manifests, as a painless mass, in the frontal region following trauma. The unusual incidence and confusing presentation require the clinicians to thoroughly understand its presentation and diagnosis. Diagnosis is typically made on history and physical examination, but it can be confirmed by duplex ultraso...
