particle statistics (uncountable)

Used other than figuratively or idiomatically: see particle,‎ statistics.
(statistical mechanics, quantum mechanics) Any of certain theories, in classical physics or (particularly) quantum mechanics, that model the behaviour of collections of particles of identical type.

  This circumstance, which is much different from classical particle statistics, reflects the way in which states are counted in Bose-Einstein statistics.

  A choice of particle statistics in quantum mechanics is equivalent to choosing representations U_n, of π₁(M_n), for all n, in the quantization procedure described in §1.2; see (1.3).
  
  Thus, for a system of point particles in d > 3 dimensional, physical space, particle statistics is described by the symmetry character of wave functions under permutations of particle positions.
- 2005, Avinash Khare, Fractional Statistics and Quantum Theory, 2nd edition, World Scientific, page 5:
  The path dependence of the interchange is all important since it relates the quantum mechanical concept of particle statistics to the topology of the configuration space.
