CMS ridge effect at LHC as a manifestation of bremsstrahlung of gluons off quarks accelerated in a strong color field

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...

Summary: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 bremsstrahlung of quarks moving with acceleration defined by the string tension. The smallness of azimuthal angle difference Δ φ along with large Δ η at large multiplicities in this interval of p T are natural in this mechanism. The mechanism predicts also bremsstrahlung photons with mean values of p T ≈2.9 and 0.72 GeV.
