The Sine-Gordon Solitons as a N-Body Problem
Olivier Babelon, Denis Bernard
We consider the N-soliton solutions in the sine-Gordon model as a N-body problem. This leads to a relativistic generalization of the Calogero model first introduced by Ruijsenaars.…
Graph Rings and Integrable Perturbations of Superconformal Theories
P. Di Francesco, F. Lesage, J. -B. Zuber
We show that the connection between certain integrable perturbations of superconformal theories and graphs found by Lerche and Warner extends to a broader class. These pertur…
Ramond Sector Characters and N=2 Landau-Ginzburg Models
P. Di Francesco, S. Yankielowicz
We give a direct proof of the new "product" expression for the Ramond sector characters of N=2 minimal models recently suggested by E. Witten. Our construction allows us to general…
A Renormalization Group Study of Helimagnets in D=2+EPSILON Dimensions
P. Azaria, B. Delamotte, F. Delduc +1
We study a non linear sigma model describing the phase transition of N-components helimagnets up to two loop order in dimensions. It i…
Angular Intermittency in QCD Jets
Ph. Brax, J. -L. Meunier, R. Peschanski
Using two methods, via fluctuations and correlations, an analytical formula is derived for the factorial multiplicity moments in a QCD jet at the Double Leading Logarithm accuracy.…
