Center symmetry and the orientifold planar equivalence
Luigi Del Debbio, Agostino Patella
We study the center symmetry of SU(N) gauge theories with fermions in the two-index representations, by computing the effective potential of the Polyakov loop in the large-mass exp…
Theta dependence of SU(N) gauge theories in the presence of a topological term
Ettore Vicari, Haralambos Panagopoulos
We review results concerning the theta dependence of 4D SU(N) gauge theories and QCD, where theta is the coefficient of the CP-violating topological term in the Lagrangian. In part…
Quenched mesonic spectrum at large N
Luigi Del Debbio, Biagio Lucini, Agostino Patella +1
We compute the masses of the and of the mesons in the quenched approximation on a lattice with fixed lattice spacing for SU() gauge theory…
Highest states in light-cone superstring
Matteo Beccaria, Gian Fabrizio De Angelis, Luigi Del Debbio +1
We study the highest states in the compact rank-1 sectors of the AdS5 X S5 superstring in the framework of the recently proposed light cone Bethe Ansatz equations. In the su(1|1) s…
Bethe Ansatz solutions for highest states in SYM and AdS/CFT duality
Matteo Beccaria, Luigi Del Debbio
We consider the operators with highest anomalous dimension in the compact rank-one sectors and of super Yang-Mills. We stud…
Free energy and theta dependence of SU(N) gauge theories
L. Del Debbio, H. Panagopoulos, E. Vicari
We study the dependence of the free energy on the CP violating angle theta, in four-dimensional SU(N) gauge theories with N >= 3, and in the large-N limit. Using the Wilson lattice…
