Abstract

We present a new computational technique to evaluate divergent loop diagrams in renormalizable cavity field theories. The method, which is based on dimensional regularization, is applied to the case of the linearly divergent quark self-energy or Lamb shift in cavity QCD.

Newton's gravitation-force's classical average proof of a Verlinde's conjecture
2018, Physica A: Statistical Mechanics and its Applications
Citation Excerpt :
The main technical ingredient of our proceedings is dimensional regularization (DR). DR [3,4] constitutes one of the greatest advances in the theoretical physics of the last 45 years, with applications in several branches of physics (see, for instance, [5–58]. It is well known that, at a quantum field theory level, DR cannot cope with the gravitational field, since it is non-renormalizable.
A surprising, gravity related Verlinde-conjecture, that generated immense interest, asserts that gravity is an emergent entropic force. We provided a classical proof of the assertion in [doi.org/j.physa.2018.03.019]. Here, we classically prove a related, second Verlinde-conjecture. This states that, at very large distances ( $r_{0}$ ), gravity departs from its classical nature and begins to decay linearly with $r_{0}$ .

DR [1,2] constitutes one of the greatest advances in the theoretical physics of the last 45 years, with applications in several branches of physics (see, for instance, [3–56]).
It is believed that the canonical gravitational partition function $Z$ associated to the classical Boltzmann–Gibbs (BG) distribution $\frac{e^{- β H}}{Z}$ cannot be constructed because the integral needed for building up $Z$ includes an exponential and thus diverges at the origin. We show here that, by recourse to (1) the analytical extension treatment obtained for the first time ever, by Gradshteyn and Rizhik, via an appropriate formula for such case and (2) the dimensional regularization approach of Bollini and Giambiagi’s (DR), one can indeed obtain finite gravitational results employing the BG distribution. The BG treatment is considerably more involved than its Tsallis counterpart. The latter needs only dimensional regularization, the former requires, in addition, analytical extension.
Dimensionally regularized Tsallis’ statistical mechanics and two-body Newton's gravitation
2018, Physica A: Statistical Mechanics and its Applications
Typical Tsallis’ statistical mechanics’ quantifiers like the partition function and the mean energy exhibit poles. We are speaking of the partition function $Z$ and the mean energy $〈 U 〉$ . The poles appear for distinctive values of Tsallis’ characteristic real parameter $q$ , at a numerable set of rational numbers of the $q$ -line. These poles are dealt with dimensional regularization resources. The physical effects of these poles on the specific heats are studied here for the two-body classical gravitation potential.
Nucleon observables and loop diagrams in cavity QCD
1996, Annals of Physics
Using a technique which is based on dimensional regularization, loop corrections to vertex diagrams of a massless quark moving in a spherical cavity are calculated in an arbitrary covariant gauge. Including the finite one-gluon-exchange diagrams, the corrections to the magnetic moments, vector and axial vector coupling constants, and the various r.m.s. radii of the nucleon are evaluated to orderα_S. The results are compared with experimental data and previous calculations.

Coupling the scalar-isoscalar 'q<sup>2</sup>q<sup>2</sup> meson' to the nucleon
1994, Physics Letters B
We investigate the coupling of the nucleon to the lowest scalar-isoscalar $q^{2} q^{2}$ state, that is predicted at 670 MeV/c² in the framework of cavity QCD to order α_s. The $q^{2} q^{2}$ nucleon vertex is evaluated in the $^{3} P_{0} q q$ pair creation model. Adjusting the ³P₀ strength to fit the NNπ coupling constant, the calculated $q^{2} q^{2}$ nucleon vertex agrees very well with the NNα vertices used in one-boson-exchange models of the nucleon-force.
