Chirally symmetric quark description of low energy π-πscattering
Pedro Bicudo, Stephen Cotanch, Felipe Llanes-Estrada +3
Weinberg's theorem for π-πscattering, including the Adler zero at threshold in the chiral limit, is analytically proved for microscopic quark models that preserve chiral symmetry.…
Black hole collision with a scalar particle in three dimensional anti-de Sitter spacetime
Vitor Cardoso, Jose' P. S. Lemos
We study the collision between a BTZ black hole and a test particle coupled to a scalar field. We compute the power spectrum, the energy radiated and the plunging waveforms for thi…
Warped Solitonic Deformations and Propagation of Black Holes in 5D Vacuum Gravity
Sergiu I. Vacaru, D. Singleton
In this paper we use the anholonomic frames method to construct exact solutions for vacuum 5D gravity with metrics having off-diagonal components. The solutions are in general anis…
Conformal Orbifold Partition Functions from Topologically Massive Gauge Theory
P. Castelo Ferreira, I. I. Kogan, R. J. Szabo
We continue the development of the topological membrane approach to open and unoriented string theories. We study orbifolds of topologically massive gauge theory defined on the geo…
Orbitally excited D and B mesons in the approach of the QCD string with quarks at the ends
Yu. S. Kalashnikova, A. V. Nefediev
In this letter we discuss the masses and the splittings of 1(2S+1)P_J states in the spectrum of D and B mesons, as they appear in the approach of the QCD string with quarks at the…
From Regge Behavior to DGLAP Evolution
L. Csernai, L. Jenkovszky, K. Kontros +3
We study the interface between Regge behavior and DGLAP evolution in a non-perturbative model for the nucleon structure function based on a multipole pomeron exchange. This model p…
