  The possibility of formation of Bose-Einstein Condensation (BEC) is studied
in $pp$ collisions at $\sqrt s$ = 7 TeV at the Large Hadron Collider. A
thermodynamically consistent non-extensive formulation of the identified hadron
transverse momentum distributions is used to estimate the critical temperature
required to form BEC of charged pions, which are the most abundant species in a
multi-particle production process in hadronic and nuclear collisions. The
obtained results have been contrasted with the systems produced in Pb-Pb
collisions to have a better understanding. We observe an explicit dependency of
BEC critical temperature and number of particles in the pion condensates on the
non-extensive parameter $q$, which is a measure of degree of non-equilibrium --
as $q$ decreases, the critical temperature increases and approaches to the
critical temperature obtained from Bose-Einstein statistics without
non-extensivity. Studies are performed on the final state multiplicity
dependence of number of particles in the pion condensates in a wide range of
multiplicity covering hadronic and heavy-ion collisions, using the inputs from
experimental transverse momentum spectra.
