Hexagons and correlators in the fishnet theory
(2019-11-01)
We investigate the hexagon formalism in the planar 4d conformal fishnet theory. This theory arises from N = 4 SYM by a deformation that preserves both conformal symmetry and integrability. Based on this relation, we obtain ...
The S-matrix bootstrap. Part III: higher dimensional amplitudes
(2019-12-01)
We consider constraints on the S-matrix of any gapped, Lorentz invariant quantum field theory in 3+1 dimensions due to crossing symmetry, analyticity and unitarity. We extremize cubic couplings, quartic couplings and ...
N=2 supersymmetric QCD and elliptic potentials
(Springer, 2014-11-06)
We investigate the relation between the four dimensional N = 2 SU(2) super Yang-Mills theory with four fundamental flavors and the quantum mechanics model with Treibich-Verdier potential described by the Heun equation in ...

Optimized δ expansion for the Walecka model

Non-perturbative fixed points and renormalization group improved effective potential
(Elsevier B.V., 2014-12-12)
The stability conditions of a renormalization group improved effective potential have been discussed in the case of scalar QED and QCD with a colorless scalar. We calculate the same potential in these models assuming the ...
Gluon mass generation in the PT-BFM scheme
(2006-12-01)
In this article we study the general structure and special properties of the Schwinger-Dyson equation for the gluon propagator constructed with the pinch technique, together with the question of how to obtain infrared ...

Chiral transition of fundamental and adjoint quarks
(Elsevier B.V., 2014-01-20)
The chiral symmetry breaking transition of quarks in the fundamental and adjoint representation is studied in a model where the gap equation contains two contributions, one containing a confining propagator and another ...
NONPERTURBATIVE HQET AT ORDER 1/m
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2010)
We summarize the first results for masses and decay constants of bottom-strange (pseudo-scalar and vector) mesons from nonperturbatively renormalized heavy-quark effective theory (HQET), using lattice-QCD simulations in ...
