Gauge Transformations, Twisted Poisson Brackets and Hamiltonization of Nonholonomic Systems

In this paper we study the problem of Hamiltonization of nonholonomic systems from a geometric point of view. We use gauge transformations by 2-forms (in the sense of evera and Weinstein in Progr Theoret Phys Suppl 144:145 154 2001) to construct different ...

One-loop adjoint masses for non-supersymmetric intersecting branes

Alessandro Vichi

We consider breaking of supersymmetry in intersecting D-brane configurations by slight deviation of the angles from their supersymmetric values. We compute the masses generated by radiative corrections for the ad joint scalars on the brane world-volumes. I ...

Renormalization and blow up for the critical Yang-Mills problem

Joachim Krieger, Daniel Tataru

We consider the Yangs-Mills equations in 4 + 1 dimensions. This is the energy critical case and we show that it admits a family of solutions which blow up in finite time. They are obtained by the spherically symmetric ansatz in the SO(4) gauge group and re ...

4d Lorentzian Holst action with topological terms

Danilo Jimenez Rezende

We study the Hamiltonian formulation of the general first order action of general relativity compatible with local Lorentz invariance and background independence. The most general simplectic structure (compatible with diffeomorphism invariance and local Lo ...

Anomalous solitons

Matthias Schmid

Solitons are stable, non-singular solutions to the classical equations of motion of non-linear field theory. Their energy is localized and finite and their shape remains unaltered during propagation. For this reason they represent particle-like states in f ...

Unity of supersymmetry breaking models

Riccardo Rattazzi

We examine the models with gauge group U(1)(k-1) x Pi(i=1)(k) SU(n(i)), which are obtained from decomposing the supersymmetry breaking model of Affleck, Dine and Seiberg containing an antisymmetric tensor field. We note that all of these models are distinc ...

Radiative Quark Masses Constrained by the Gauge Group Only

Riccardo Rattazzi

We discuss the possibility of obtaining the observed pattern of quark masses and mixings as a consequence of radiative corrections, gauge invariance and particle content of the theory. We do not allow any kind of additional symmetry, such as family and dis ...
