Vector boson pair creation in noncommutative Rindler spacetime with an external field

In this work, we investigate the dynamics of the noncommutative Duffin-Kemmer-Petiau (DKP) field in a (1+1)-dimensional Rindler spacetime in the presence of an external background field. By employing the Seiberg-Witten maps and the Moyal star product, we derive the modified DKP equation up to first order in the noncommutativity parameter. Exact analytical solutions of the wave equation for spin-1 bosonic particles are obtained within this noncommutative curved geometry. Using Bogoliubov transformation techniques, we derive both the pair-creation density and the corresponding total number of created particles. Our analysis reveals that the noncommutative structure of spacetime significantly affects the particle production process: specifically, the rate of particle creation decreases inversely with the noncommutativity scale. This behavior reveals a nontrivial interplay between noncommutativity and gravitational effects and remains consistent with the fundamental principles of quantum field theory in curved spacetime.
