A miniature 12 MeV race-track microtron for medical applications is under construction at the Technical University of Catalonia in collaboration with several Spanish centers and companies and the Skobeltsyn Institute of Nuclear Physics of the Moscow

Implementation of low-energy injection schemes in race-track microtron (RTM) designs requires a better understanding of the longitudinal beam dynamics. Unlike the high-energy case a low-energy beam slips in phase with respect to the accelerating fiel

We review the present status of how astronomical observations allow to constrain the evolution of fundamental constants of nature. The main observational constraints on the variation of the gravitational constant, on the fine structure constant and o

We construct the second variation Lagrangian for the Randall*Sundrum model with two branes, study its gauge invariance, and introduce and decouple the corresponding equations of motion. For the physical degrees of freedom in this model, we find the e

The design and tuning of end magnets of a compact 12MeV race-track microtron (RTM) which is under construction at the Technical University of Catalonia are described. These magnets are systems composed of four dipoles with a Rare-Earth Permanent Magn

The compact race-track microtron (RTM) with a maximum energy of 12 MeV that is under construction at the Technical University of Catalonia consists of a quadrupole lens for horizontal focusing of the beam and four dipole magnets for the extraction of

The vacuum expectation value of the Wilson loop functional in pure Yang-Mills theory on an arbitrary two-dimensional orientable manifold is studied. We consider the calculation of this quantity for the abelian theory in the continuum case and for the

The one-loop effective potential in a scalar theory with quartic interaction on the spaceM 4×T n forn=2 is calculated and is shown to be unbounded from below. This is an indication of a possible instability of the vacuum of theλψ 4 model onM 4, wh

Invariant connections with torsion on simple group manifolds $S$ are studied and an explicit formula describing them is presented. This result is used for the dimensional reduction in a theory of multidimensional gravity with curvature squared terms
