Deformed conformal and super-Poincaré symmetries in the non-(anti)commutative spaces
Rabin Banerjee, Choonkyu Lee, Sanjay Siwach
Generators of the super-Poincaré algebra in the non-(anti)commutative superspace are represented using appropriate higher-derivative operators defined in this quantum superspace. A…
Noncommutativity from Embedding Techniques
Saurav Samanta
We apply the embedding method of Batalin-Tyutin for revealing noncommutative structures in the generalized Landau problem. Different types of noncommutativity follow from different…
Superfield Approach To Nilpotent Symmetries For QED From A Single Restriction: An Alternative To The Horizontality Condition
R. P. Malik
We derive together the exact local, covariant, continuous and off-shell nilpotent Becchi-Rouet-Stora-Tyutin (BRST) and anti-BRST symmetry transformations for the U(1) gauge field (…
Superfield Approach To Exact And Unique Nilpotent Symmetries
R. P. Malik
In the framework of usual superfield approach, we derive the exact local, covariant, continuous and off-shell nilpotent Becchi-Rouet-Stora-Tyutin (BRST) and anti-BRST symmetry tran…
A BRST gauge-fixing procedure for Yang-Mills theory on sphere
Rabin Banerjee, Shinichi Deguchi
A gauge-fixing procedure for the Yang-Mills theory on an n-dimensional sphere (or a hypersphere) is discussed in a systematic manner. We claim that Adler's gauge-fixing condition u…
Non(anti) commutativity for open superstrings
Biswajit Chakraborty, Sunandan Gangopadhyay, Arindam Ghosh Hazra +1
Non(anti)commutativity in an open free superstring and also one moving in a background anti-symmetric tensor field is investigated. In both cases, the non(anti)commutativity is sho…
