Higher Dimensional SUSY Quantum Mechanics
Ashok Das, Sergio. A. Pernice
Higher dimensional supersymmetric quantum mechanics is studied. General properties of the two dimensional case are presented. For three spatial dimesions or higher, a spin structur…
``Induced'' Super-Symmetry Breaking with a Vanishing Vacuum Energy
Ashok Das, Sergio A. Pernice
A new mechanism for symmetry breaking is proposed which naturally avoids the constraints following from the usual theorems of symmetry breaking. In the context of super-symmetry, f…
On the Divergence of Perturbation Theory. Steps Towards a Convergent Series
S. A. Pernice, G. Oleaga
The mechanism underlying the divergence of perturbation theory is exposed. This is done through a detailed study of the violation of the hypothesis of the Dominated Convergence The…
Fully Relativistic Quark Models for Heavy-Light Systems
S. A. Pernice
A fully relativistic quark model is constructed and applied to the study of wave-functions as well as the spectrum of heavy-light mesons. The free parameters of the model are a con…
Nonperturbative Renormalon Structure of Infrared Unstable Theories
A. Duncan, S. Pernice
The properties of a generalized version of the Borel Transform in infrared unstable theories with dynamical mass generation are studied. The reconstruction of the nonperturbative s…
Pion Wavefunctions and Truncation Sensitivity of QCD Sum Rules
A. Duncan, S. Pernice, E. Schnapka
The systematic errors inherent in the QCD sum rule approach to meson wavefunctions are examined in the context of QCD in 1+1 spacetime dimensions in the large N limit where the the…
