Query: Massive Spinning Relativistic Particle: Revisited Under BRST and
  Supervariable Approaches   We discuss the continuous and infinitesimal gauge, supergauge,
reparameterization, nilpotent Becchi-Rouet-Stora-Tyutin (BRST) and anti-BRST
symmetries and derive corresponding nilpotent charges for the one
(0+1)-dimensional (1D) massive model of a spinning relativistic particle. We
exploit the theoretical potential and power of the BRST and supervariable
approaches to derive the (anti-)BRST symmetries and coupled (but equivalent)
Lagrangians for this system. In particular, we capture the off-shell nilpotency
and absolute anticommutatvity of the conserved (anti-)BRST charges within the
framework of the newly proposed (anti-)chiral supervariable approach (ACSA) to
BRST formalism where only the (anti-)chiral supervariables (and their suitable
super expansions are taken into account along the Grassmannian direction(s)).
One of the novel observations of our present investigation is the derivation of
the Curci-Ferrari (CF)-type restriction by the requirement of the absolute
anticommutatvity of the (anti-)BRST charges in the ordinary space. We obtain
the same restriction within the framework of ACSA to BRST formalism by (i) the
symmetry invariance of the coupled Lagrangians, and (ii) the proof of the
absolute anticommutatvity of the conserved and nilpotent (anti-)BRST charges.
The observation of the anticommutativity property of the (anti-)BRST charges is
a novel result in view of the fact that we have taken into account only the
(anti-)chiral super expansions.
