  The mid-rapidity transverse momentum spectra of hadrons (p, p-bar, K+, K-,
K0-short, phi, {\Lambda}, {\Lambda}-bar, {\Xi},{\Xi}-bar, ({\Xi} + {\Xi}-bar),
{\Omega}, and {\Omega}-bar) and the available rapidity distributions of the
strange hadrons K0-short, ({\Lambda} + {\Lambda}-bar), ({\Xi} + {\Xi}-bar)
produced in p-p collisions at LHC energy root(sNN) = 0.9 TeV have been studied
using a Unified Statistical Thermal Freeze-out Model (USTFM). The calculated
results are found to be in good agreement with the experimental data. The
theoretical fits of the transverse momentum spectra using the model
calculations provide the thermal freeze-out conditions in terms of the
temperature and collective flow parameters for different hadronic species. The
study reveal the presence of significant collective flow and a well defined
temperature in the system thus indicating the formation of a thermally
equilibrated hydrodynamic system in p-p collisions at LHC. Moreover, the fits
to the available experimental rapidity distributions data of strange hadrons
show the effect of almost complete transparency in p-p collisions at LHC. The
model incorporates longitudinal as well as a transverse hydrodynamic flow. The
contributions from heavier decay resonances have also been taken into account.
We have also imposed the criteria of exact strangeness conservation in the
system.
