  The recently reported effect of long-range near-side angular correlations at
LHC occurs for large multiplicities of particles with
$1\,GeV\,<p_T\,<\,3\,GeV$. To understand the effect several possibilities have
been discussed. In the letter we propose a simple qualitative mechanism which
corresponds to gluon bremstralung of quarks moving with acceleration
appropriate to the quark--anti-quark string. The smallness of azimuthal angle
difference $\Delta \phi$ along with large $\Delta \eta$ at large multiplicities
in this interval of $p_T$ are natural in the mechanism. The mechanism predicts
also bremstralung photons with mean values of $p_T \approx 2.9$ and
$0.72\,GeV$.
