Ridge Formation Induced by Jets in pp Collisions at 7 TeV
Abstract
An interpretation of the ridge phenomenon found in pp collisions at 7 TeV is given in terms of enhancement of soft partons due to energy loss of semihard jets. A description of ridge formation in nuclear collisions can directly be extended to pp collisions, since hydrodynamics is not used, and azimuthal anisotropy is generated by semihard scattering. Both the pT and multiplicity dependencies are well reproduced. Some suggestions are made about other observables.
