An excursion into the string spectrum
Journal of High Energy Physics, 2023 We propose a covariant technique to excavate physical bosonic string states by entire trajectories rather than individually. The approach is based on Howe duality: the string’s spacetime Lorentz algebra commutes with a certain inductive limit of sp ...

Einstein gravity from the N = 4 $$ \mathcal{N}=4 $$ spinning particle
Journal of High Energy Physics, 2018 We obtain a manifestly background independent BRST quantization of the N = 4 $$ \mathcal{N}=4 $$ supersymmetric spinning particle. We show that nilpotency of the BRST charge Q implies the Einstein equations admitting a cosmological constant of indefinite

A worldline theory for supergravity
Journal of High Energy Physics, 2020 The N $$ \mathcal{N} $$ = 4 supersymmetric spinning particle admits several consistent quantizations, related to the gauging of different subgroups of the SO(4) R-symmetry on the worldline.

BRST-anti-BRST covariant theory for the second class constrained systems. A general method and examples [PDF]
, 1998 The BRST-anti-BRST covariant extension is suggested for the split involution quantization scheme for the second class constrained theories. The constraint algebra generating equations involve on equal footing a pair of BRST charges for second class ...

Finite BRST–antiBRST transformations in Lagrangian formalism
Physics Letters B, 2014 We continue the study of finite BRST–antiBRST transformations for general gauge theories in Lagrangian formalism initiated in [1], with a doublet λa, a=1,2, of anticommuting Grassmann parameters, and find an explicit Jacobian corresponding to this change

Irreducible Hamiltonian BRST analysis of Stueckelberg coupled p-form gauge theories [PDF]
, 1999 The irreducible Hamiltonian BRST symmetry for p-form gauge theories with Stueckelberg coupling is derived. The cornerstone of our approach is represented by the construction of an irreducible theory that is equivalent from the point of view of the BRST ...

Triplectic Quantization of W2 gravity [PDF]
, 2000 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 ...

A note on BRST quantization of SU(2) Yang-Mills mechanics [PDF]
, 2005 The quantization of SU(2) Yang-Mills theory reduced to 0+1 space-time dimensions is performed in the BRST framework. We show that in the unitary gauge $A_0 = 0$ the BRST procedure has difficulties which can be solved by introduction of additional singlet

INTEGRATION MEASURE AND EXTENDED BRST-COVARIANT QUANTIZATION [PDF]
International Journal of Modern Physics A, 2002 We propose an extended BRST-invariant Lagrangian quantization scheme of general gauge theories based on explicit realization of the "modified triplectic algebra" that was announced in our previous investigation (hep-th/0104189). The algebra includes, besides the specific odd operators Va appearing in the triplectic formalism, also the odd operators Ua
