Twisted BRST symmetry in gauge theories on the <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mi>κ</mml:mi></mml:math> -Minkowski spacetime

Algebraic properties of the Becchi-Rouet-Stora-Tyutin (BRST) symmetry associated to twisted gauge occurring in $\ensuremath{\kappa}$-Poincar\'e invariant theories on $\ensuremath{\kappa}$-Minkowski space are investigated. We find that BRST operation invariance action functional can be continuously deformed together with its corresponding Leibniz rule, into a nilpotent operation, leading algebra which may viewed as noncommutative analog usual Yang-Mills algebra.
