The transverse momentum pT spectra of both hadrons and jets produced in pp collisions at beam energies from hundreds GeV to a few TeV exhibit power-law behavior of 1/pTn at high pT, with similar power indices n. The respective nonextensivity parameters for transverse momenta distributions and the global nonextensivity parameter obtained from multiplicities are compared. In particular, data on kaon to pion (charged particles) multiplicity ratio are analyzed, assuming that the reaction occurs in some nonextensive environment. The values of the corresponding nonextensivity parameters were found to be similar, strongly indicating the existence of a common mechanism behind all these observables.

We are interested in long-lived heavy charged particles because they would be possible SUSY particle candidats. This paper shows our preliminary results of long-lived heavy charged particles generation using  PYTHIA 8. More than 107 events have been generated with pp  collisions at energy in the center of mass = 13 TeV and about  3.27 105  long-lived heavy charged particles candidates have been found in the geometric acceptance of the LHCb detector. Long-lived  heavy charged particles has mass 1.025 TeV/c2 and lifetime   157.7 nanoseconds, therefore they can travel throughout all subdetectors.  We try not only calculate their acceptance in function of  transverse momentum  and rapidity but also combine a pair of candidats  with opposite charge in order to reconstruct their invariant mass. In the next step, we have intention to identify stau using the informations from subdetectors such as the inner tracker and the muon chambers.
