Query: Indication of transverse radial flow in high-multiplicity proton-proton
  collisions at the Large Hadron Collider   We analyze the measured spectra of $\pi^\pm$, $K^\pm$, $p$($\bar p$) in $pp$
collisions at $\sqrt {s}$ = 0.9, 2.76 and 7 TeV, in the light of blast-wave
model to extract the transverse radial flow velocity and kinetic temperature at
freeze-out for the system formed in $pp$ collisions. The dependency of the
blast-wave parameters on average charged particle multiplicity of event sample
or the `centrality' of collisions has been studied and compared with results of
similar analysis in nucleus-nucleus ($AA$) and proton-nucleus ($pA$)
collisions. We analyze the spectra of $K_{s}^0$, $\Lambda$($\bar \Lambda$) and
$\Xi^-$ also to see the dependence of blast-wave description on the species of
produced particles. Within the framework of the blast-wave model, the study
reveals indication of collective behavior for high-multiplicity events in $pp$
collisions at LHC. Strong transverse radial flow in high multiplicity $pp$
collisions and its comparison with that in $pA$ and $AA$ collisions match with
predictions from a very recent theoretical work [Shuryak and Zahed 2013
arXiv:1301.4470] that addresses the conditions for applicability of
hydrodynamics in $pp$ and $pA$ collisions.
