Sigma-resonance and convergence of chiral perturbation theory
D. J. Cecile, Shailesh Chandrasekharan
The dimensionless parameter , where is the pion decay constant in the chiral limit and is the pion mass at leading order in the quark mass, is expect…
A new computational approach to lattice quantum field theories
Shailesh Chandrasekharan
Developments in algorithms over the past decade suggest that there is a new computational approach to a class of quantum field theories. This approach is based on rewriting the par…
Role of the -resonance in determining the convergence of chiral perturbation theory
D. J. Cecile, Shailesh Chandrasekharan
The dimensionless parameter , where is the pion decay constant and is the pion mass, is expected to control the convergence of chiral perturbat…
Absence of vortex condensation in a two dimensional fermionic XY model
D. J. Cecile, Shailesh Chandrasekharan
Motivated by a puzzle in the study of two dimensional lattice Quantum Electrodynamics with staggered fermions, we construct a two dimensional fermionic model with a global U(1) sym…
