Rationally extended shape invariant potentials in arbitrary D-dimensions associated with exceptional polynomials
Rajesh Kumar Yadav, Nisha Kumari, Avinash Khare +1
Rationally extended shape invariant potentials in arbitrary D-dimensions are obtained by using point canonical transformation (PCT) method. The bound-state solutions of these exact…
A black potential for spin less particles
Ananya Ghatak, Mohammad Hasan, Bhabani Prasad Mandal
We consider the most general non-Hermitian Hulthen potential to study the scattering of spin-less relativistic particles. The conditions for CC, SS and CPA are obtained analyticall…
Reciprocity in parity violating non-Hermitian systems
Ananya Ghatak, Brijesh Kumar Mourya, Raka Dona Ray Mandal +1
Reciprocity is shown so far only when the scattering potential is either real or parity symmetric complex. We extend this result for parity violating complex potential by consideri…
Finite field-dependent BRST symmetry for ABJM theory in superspace
Mir Faizal, Sudhaker Upadhyay, Bhabani Prasad Mandal
In this paper we analyse the ABJM theory in superspace. Firstly we study the linear and non-linear BRST transformations for the ABJM theory. Then we derive the finite…
Generalized BRST symmetry for arbitrary spin conformal field theory
Sudhaker Upadhyay, Bhabani Prasad Mandal
We develop the finite field-dependent BRST (FFBRST) transformation for arbitrary spin-s conformal field theories. We discuss the novel features of the FFBRST transformation in thes…
Emergence of Lowenstein-Zimmermann mass terms for QED
Sudhaker Upadhyay, Manoj Kumar Dwivedi, Bhabani Prasad Mandal
In this paper we consider a super-renormalizable theory of massless QED in dimensions and discuss their BRST symmetry transformation. By extending the BRST transformation w…
