U(1) Problem Revisited
H. Banerjee, Gautam Bhattacharya
In the anomaly equation for the singlet axial current the chiral limit of the quark mass term does not vanish but comprises contribution from fermion zero modes whose integral exac…
A Critical String Theory in 3+1 Dimensions
J. S. Bhattacharyya, Gautam Bhattacharya
Redefining the vacuum state of a free twofold N=1 covariant supersymmetric string action as the one with all the world sheet fermionic excited states occupied, makes the theory ano…
Perturbative analysis of multiple-field cosmological inflation
Joydev Lahiri, Gautam Bhattacharya
We develop a general formalism for analyzing linear perturbations in multiple-field cosmological inflation based on the gauge-ready approach. Our inflationary model consists of an…
Criteria for Exact Solubility of Relativistic Field Theories by Scattering Transform
Gautam Bhattacharya
Scattering transform is a well known powerful tool for quantisation of field theories in (1+1) dimensions. Conventionally only those models whose classical counterparts admit a Lax…
A Generalized Gauge Invariant Regularization of the Schwinger Model
G. Bhattacharya, A. Ghosh, P. Mitra
The Schwinger model is studied with a new one - parameter class of gauge invariant regularizations that generalizes the usual point - splitting or Fujikawa schemes. The spectrum is…
Heavy Charged Lepton Pair Production Through Photon Fusion at Hadron Supercolliders
G. Bhattacharya, P. A. Kalyniak, K. A. Peterson
The pair production of charged heavy leptons via two photon fusion is considered for hadron collisions at SSC and LHC energies. Rates for the inelastic process $pp \rightarrow γγX…
