Anomalous dimensions of finite size field strength operators in N=4 SYM

Matteo Beccaria, Valentina Forini

In the N=4 super Yang-Mills theory, we consider the higher order anomalous dimensions gamma_L(g) of purely gluonic operators Tr(F^L) where F is a component of the self-dual field s…

Large spin expansion of the long-range Baxter equation in the sl(2) sector of N=4 SYM

Matteo Beccaria, Francesca Catino

Recently, several multi-loop conjectures have been proposed for the spin dependence of anomalous dimensions of twist-2 and 3 operators in the sl(2) sector of N=4 SYM. Currently, th…

Three loop anomalous dimensions of twist-3 gauge operators in N=4 SYM

Matteo Beccaria

We propose a closed expression for the three loop anomalous dimension of a class of twist-3 operators built with gauge fields and covariant derivatives. To this aim, we solve the l…

Dirac Equation Studies in the Tunnelling Energy Zone

Stefano De Leo, Pietro Rotelli

We investigate the tunnelling zone V0 < E < V0+m for a one-dimensional potential within the Dirac equation. We find the appearance of superluminal transit times akin to the Hartman…

Twist 3 of the sl(2) sector of N=4 SYM and reciprocity respecting evolution

M. Beccaria, Yu. L. Dokshitzer, G. Marchesini

We consider the bosonic sl(2) sector of the maximally supersymmetric N=4 SYM model and show that anomalous dimension of the twist-3 single-trace composite operators built of scalar…

Universality of three gaugino anomalous dimensions in N=4 SYM

Matteo Beccaria

We study maximal helicity three gaugino operators in N=4 Super Yang-Mills theory. We show that the lowest anomalous dimension of scaling operators with generic finite spin can be e…

Anomalous dimensions at twist-3 in the sl(2) sector of N=4 SYM

Matteo Beccaria

We consider twist-3 operators in the sl(2) sector of N=4 SYM built out of three scalar fields with derivatives. We extract from the Bethe Ansatz equations of this sector the exact…

The scaling function at strong coupling from the quantum string Bethe equations

Matteo Beccaria, Gian Fabrizio De Angelis, Valentina Forini

We study at strong coupling the scaling function describing the large spin anomalous dimension of twist two operators in super Yang-Mills theory. In the spirit of AdS/…

On the supersymmetric vacua of the Veneziano-Wosiek model

Matteo Beccaria

We study the supersymmetric vacua of the Veneziano-Wosiek model in sectors with fermion number F=2, 4 at finite 't Hooft coupling lambda. We prove that for F=2 there are two zero e…

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…
