Search for a Ridge Structure Origin with Shower Broadening and Jet Quenching

Understand

We investigate the role of jet and shower parton broadening by the strong colour field in the $\Delta\eta$-$\Delta\phi$ correlation of high $p_T$ particles.

• When anisotropic momentum broadening ($\Delta p_z > \Delta p_T$) 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.
