4. Amplitudes from first principles

n 2004 it has been shown that scattering amplitudes can be expressed by
glueing together simple three-point on-shell amplitudes. These so-called
BCFW-recursion relations can for instance be used to proof the explicit
form of the n-gluon scattering amplitude as conjectured by Parke and
Taylor. Moreover, the basic building blocks, the three-point on-shell
amplitudes, are, apart from a...

6. A chiral model using unconventional SUSY and its possible applications

Dr Alvarez Pedro (Universidad de Antofagasta)

Using unconventional SUSY, we construct a model that allow us to obtain a theory that is chiral and contains dynamical gravity, therefore resembling the structure of the Standard Model and General Relativity. We review the main features of Zanelli's unconventional SUSY that allow us to couple matter fields in a gauge invariant way. We will discuss the difficulties, advantages and future tasks...

5. Skyrme model at finite density and Skyrme crystals: analytic results

Fabrizio Canfora

In this talk I will show how one can deduce exact analytic results in the Skyrme model on flat space-times using a quite remarkable mapping from the Einstein-Skyrme system. In particular, the explicit form of the critical Isospin chemical potential for one Skyrmion will be derived. Moreover, I will also describe analytically how Skryme crystals appear at finite Baryon density. Due to the...

7. Two dimensional chiral anomaly in Very Special Relativity

We discuss the Schwinger model in the formalism of Very Special Relativity. Although there is not mass from spontaneous symmetry breaking, there is a mass term coming from the SIM(2) invariant terms and the axial current stills conserved in this case. It is shown that the current when the fermion is coupled to an external electromagnetic field is modified due to the non local operator present...

26. Odderon slope in non-perturbative QCD

Carlos Contreras (Santa Maria)

In this talk we will present first numerical calculation of the Odderon intercept and slope obtained with IR-regulator approach.
