Athanasiou, C. and Lester, C. G. and Smillie, J. M. and Webber, B. R. (2006) 'Distinguishing spins in decay chains at the Large Hadron Collider.', Journal of high energy physics., 8 . p. 55.
If new particles are discovered at the LHC, it will be important to determine their spins in as model-independent a way as possible. We consider the case, commonly encountered in models of physics beyond the Standard Model, of a new scalar or fermion D decaying sequentially into other new particles C,B,A via the decay chain D→Cq, C→Blnear, B→Alfar, lnear and lfar being opposite-sign same-flavour charged leptons and A being invisible. We compute the observable 2- and 3-particle invariant mass distributions for all possible spin assignments of the new particles, and discuss their distinguishability using a quantitative measure known as the Kullback-Leibler distance.
