QUANTIZATION OF A $q$-DEFORMED FREE RELATIVISTIC PARTICLE [PDF]
A $q$-deformed free scalar relativistic particle is discussed in the framework of the BRST formalism. The $q$-deformed local gauge symmetry and reparametrization invariance of the first-order Lagrangian have been exploited for the BRST quantization of ...

Abstract The aim of this paper is to prove the existence of Hadamard states for the Maxwell equations on any globally hyperbolic spacetime. This will be achieved by introducing a new gauge fixing condition, the Cauchy radiation gauge, that will allow to suppress all the unphysical degrees of freedom. The key ingredient for achieving this gauge is a new

A Guide to Light‐Cone PDFs from Lattice QCD: An Overview of Approaches, Techniques, and Results
Within the theory of Quantum Chromodynamics (QCD), the rich structure of hadrons can be quantitatively characterized, among others, using a basis of universal nonperturbative functions: parton distribution functions (PDFs), generalized parton distributions (GPDs), transverse momentum dependent parton distributions (TMDs), and distribution amplitudes ...

Spin fields for the spinning particle
We propose an analogue of spin fields for the relativistic RNS-particle in 4 dimensions, in order to describe Ramond-Ramond states as “two-particle” excitations on the world line.

Triplectic Quantization of W2 gravity [PDF]
The role of one loop order corrections in the triplectic quantization is discussed in the case of W2 theory. This model illustrates the presence of anomalies and Wess Zumino terms in this quantization scheme where extended BRST invariance is represented ...

Exploring T‐Duality for Self‐Dual Fields
Abstract Avatars of T‐duality within Sen's formalism for self‐dual field strengths in various dimensions are studied. This formalism is shown to naturally accommodate the T‐duality relation between Type IIA/IIB theories when compactified on a circle without the need for imposing the self‐duality constraint by hand, as is usually done. The study of this

We exploit the theoretical strength of augmented version of superfield approach (AVSA) to Becchi‐Rouet‐Stora‐Tyutin (BRST) formalism to express the nilpotency and absolute anticommutativity properties of the (anti‐)BRST and (anti‐)co‐BRST conserved charges for the two (1 + 1)‐dimensional (2D) non‐Abelian 1‐form gauge theory (without any interaction ...

Soliton quantization in the BRST scheme
Abstract We apply the BRST quantization method to nonlinear field theories admitting solitonic solutions. We explicitly evaluate the quantum corrections to the soliton masses and transition amplitudes of the field operator. We compare our results with those obtained with more conventional methods.

Quantization of Weyl invariant unimodular gravity with antisymmetric ghost fields
The enforcement of the unimodularity condition in a gravity theory by means of a Lagrange multiplier leads, in general, to inconsistencies upon quantization.

Gauge-invariant spectral description of the U (1) Higgs model from local composite operators
The spectral properties of a set of local gauge-invariant composite operators are investigated in the U(1) Higgs model quantized in the ’t Hooft R ξ gauge.
