1. Parisi-Wu Quantization, CP violation and Beyond the Standard Model

Author

Kapoor, A. K.

Subjects
High Energy Physics - Phenomenology, High Energy Physics - Theory
Abstract

The Parisi-Wu scheme of quantization opens up the possibility of using anomalous fermionic gauge theories. An analysis of ultra-violet divergences reveals that the structure of counter terms is different from what is expected in conventional quantization schemes. In this letter it is argued that there exists a possible mechanism of CP violation that requires at least three generations of quarks, a result well known from a phenomenological analysis of mass mixing of quarks. A few observations on possible ways of going beyond the standard model are included., Comment: 6 pages; accepted for publication in Mod. Phys. Letters A

8. A New Approach to Axial Vector Gauge Theories

Author

Kapoor, A K

Subjects
High Energy Physics - Theory
Abstract

In an earlier paper it has been shown that the ultra violet divergence structure of anomalous U(1) axial vector gauge model in the stochastic quantization scheme is different from that in the conventional quantum field theory. Also it has been shown that the model is expected to be renormalizable. Based on the operator formalism of the stochastic quantization, a new approach to anomalous U(1) axial vector gauge model is proposed. The operator formalism provides a convenient framework for analysis of ultra violet divergences, but the computations in a realistic model become complicated. In this paper a new approach to do computations in the model is formulated directly in four dimensions. The suggestions put forward here will lead to simplification in the study of applications of the axial vector gauge theory, as well as those of other similar models, Comment: Latex 8 pages

23. Stochastic Quantization of Axial Vector Gauge Theories

Author

Kapoor, A. K.

Subjects
High Energy Physics - Theory
Abstract

The stochastic quantization scheme proposed by Parisi and Wu in 1981 is known to have differences from conventional quantum field theory in higher orders. It has been suggested that some of these new features might give rise to a mechanism to explain tiny fermion masses as arising due to radiative corrections. In view of importance for need of going beyond the standard model, in this article some features of U(1) axial vector gauge theory in Parisi Wu stochastic quantization scheme are reported. Renormalizability of a massive axial vector gague theory coupled to a massless fermion appears as one of the important conclusions., Comment: 8pages, arXive:1811.03013 was inadvertently replaced by a new file submitted to the arXive in Mar 2021.
