Moduli Fields as Quintessence and the Chameleon

Philippe Brax, Jerome Martin

We consider models where moduli fields are not stabilized and play the role of quintessence. In order to evade gravitational tests, we investigate the possibility that moduli behav…

Meson decays from string splitting

F. Bigazzi, A. L. Cotrone, L. Martucci +1

We discuss exclusive decays of large spin mesons into mesons in models of large N_c quenched QCD at strong coupling using string theory. The rate of the processes are calculated by…

Renormalization group flows for parafermionic field theory

Vladimir S. Dotsenko, Benoit Estienne

Using the renormalization group approach, the Coulomb gas and the coset techniques, the effect of slightly relevant perturbations is studied for the second parafermionic field theo…

Perturbations of Self-Accelerated Universe

Cedric Deffayet, Gregory Gabadadze, Alberto Iglesias

We discuss small perturbations on the self-accelerated solution of the DGP model, and argue that claims of instability of the solution that are based on linearized calculations are…

From Fundamental Strings to Small Black Holes

Lorenzo Cornalba, Miguel S. Costa, Joao Penedones +1

We give evidence in favour of a string/black hole transition in the case of BPS fundamental string states of the Heterotic string. Our analysis goes beyond the counting of degrees…

New predictions on meson decays from string splitting

F. Bigazzi, A. L. Cotrone

We study certain exclusive decays of high spin mesons into mesons in models of large N_c Yang-Mills with few flavors at strong coupling using string theory. The rate of the process…
