Description
We investigate the role of jet and shower parton broadening by the strong colour field in the $Δη$-$Δϕ$ correlation of high $p_T$ particles. When anisotropic momentum broadening ($Δp_z > Δp_T$) is given to jet and shower partons in the initial stage, a ridge-like structure is found to appear in the two hadron correlation. The ratio of the peak to the pedestal yield is overestimated.
