Symplectic Structure of 2D Dilaton Gravity
A. Mikovic, M. Navarro
We analyze the symplectic structure of two-dimensional dilaton gravity by evaluating the symplectic form on the space of classical solutions. The case when the spatial manifold is…
The Three-Loop Lattice Free Energy
B. Alles, M. Campostrini, A. Feo +1
We calculate the free energy of SU(N) gauge theories on the lattice, to three loops. Our result, combined with Monte Carlo data for the average plaquette, gives a more precise esti…
Determination of Gauge Couplings to Quarks and Leptons at Future Hadron Colliders
F. del Aguila, Mirjam Cvetic, Paul Langacker
We point out that at future hadron colliders the ratio of cross sections for in two rapidity bins is a useful probe of the relative couplings of the …
Wave Functions of the Induced 2D-Gravity
J. Navarro-Salas, M. Navarro, V. Aldaya
We consider the induced d-gravity in the minisuperspace approach. The general solution to the Wheeler-DeWitt equation is given in terms of different kind of Bessel functions of…
Renormalization and topological susceptibility on the lattice: SU(2) Yang-Mills theory
Bartomeu Alles, Massimo Campostrini, Adriano Di Giacomo +2
The renormalization functions involved in the determination of the topological susceptibility in the SU(2) lattice gauge theory are extracted by direct measurements, without relyin…
Semileptonic and Decays and the Chiral Anomaly at One-loop
Ll. Ametller, J. Bijnens, A. Bramon +1
We calculate the corrections to the anomalous form factors appearing in , and decays in Chiral Perturbation Theory. The relevant dim…
