From Nuclear To Sub-Hadronic Physics : A Global View Of Indian Efforts
Asoke N Mitra
A panoramic view seeks to trace the principal ideas governing the phenomenal growth of Nuclear Physics from a modest beginning in the Thirties, to an all-embracing field now protru…
Minimum Of QCD Effective Action As Test Of QCD Confinement Parameter
A. N. Mitra
A new approach to the non-perturbative regime of QCD is proposed by introducing a (non-hermitian) field related to the usual gluon field by = w…
Temperature Dependence of Gluon and Quark Condensates as from Linear Confinement
A. N. Mitra, W-Y. P. Hwang
The gluon and quark condensates and their temperature dependence are investigated within QCD premises. The input for the former is a gauge invariant kernel made up of the dire…
Markov-Yukawa Transversality On Covariant Null-Plane: Baryon Form Factor And Magnetic Moments
A. N. Mitra, B. M. Sodermark
The baryon- vertex function governed by the Markov-Yukawa Transversality Principle (), is formulated via the Covariant Null-Plane Ansatz () as a 3-body generalizat…
A Dynamical Principle For The Salpeter Equation
A. N. Mitra
The `Salpeter Equation' which has long been known as the 3D version of the 4D Bethe-Salpeter Equation under the Instantaneous Approximation, has a well-defined rationale that stems…
Three-Quark Bethe-Salpeter Vertex Function Under Pairwise Gluon-Exchange-Like Interaction : Application to n-p Mass Difference
A. Sharma, A. N. Mitra
A qqq BSE formalism based on an input 4-fermion Lagrangian of `current' u,d quarks, is employed for the construction of a relativistic qqq-wave function) via the BSE. Chiral invari…
