  Using superspace unitary operator formalism, we derive various (anti-)BRST
symmetry transformations explicitly for the non-Abelian 2-form gauge theories.
We introduce a new Lagrangian with a coupling of matter fields not only with
1-from background field but also with a 2-form field. Moreover, the two gauge
fields couple mutually as well. A new covariant derivative involving the 2-form
gauge field is introduced. We also put forth a conjecture to generalise this
idea to any p-form gauge theory.
