In the classical probability theory a sum of probabilities of three pairwise exclusive events is always bounded by one. This is also true in quantum mechanics if these events are represented by pairwise orthogonal projectors. However, this might not be true if the three events refer to a system of indistinguishable particles. We show that one can find three pairwise exclusive events for a system of three bosonic particles whose corresponding probabilities sum to 3/2. This can be done under…

Contextuality of identical particles
A generalisation of quantum contextuality to the case of many indentical particles is presented. The model consists of a finite collection of modes that can be occupied by N particles, either bosons
Generalized Probabilistic Description of Noninteracting Identical Particles.
TLDR
An operational description of identical noninteracting particles in multiports looks for physically motivated restrictions that explain their bunching probabilities and focuses on a symmetric 3-port in which a triple of superquantum particles admitted by the generalized probabilistic framework would bunch with a probability of 3/4.
Monogamy of Particle Statistics in Tripartite Systems Simulating Bosons and Fermions.
TLDR
It is shown that another type of correlation, indistinguishability, is also restricted by some form of monogamy, namely, if particles A and B simulate bosons, then A and C cannot perfectly imitate fermions.
Bosonic indistinguishability-dependent contextuality
We uncover a form of quantum contextuality that connects maximal contextuality to boson indistinguihability in a similar way maximal nonlocality with respect to the Clauser-Horne-Shimony-Holt Bell
