Abstract: We study the anomalous scale symmetry breaking effects on the proton mass in QCD due to quantum fluctuations at ultraviolet scales. We confirm that a novel contribution naturally arises as a part of the proton… read more here.

Abstract: We study relativistic fermions in three euclidean dimensions with four- and six-fermion interactions of the Gross-Neveu type. In the limit of many fermion flavors, and besides the isolated free fixed point, the theory displays a… read more here.

Abstract: Scalar fields, ${\ensuremath{\phi}}_{i}$, can be coupled nonminimally to curvature and satisfy the general criteria: (i) the theory has no mass input parameters, including ${M}_{P}=0$; (ii) the ${\ensuremath{\phi}}_{i}$ have arbitrary values and gradients, but undergo a… read more here.
