Small collision systems exhibit collective effects like those seen in AA collisions, which sets the foundation to postulate the formation of a QGP even in small systems.
While indeed most if not all observations between pPb and PbPb at the LHC look alike, clear final state effects as charged particle or jet suppression induced by parton energy loss as known from hot nuclear matter have not...
In this work a study of the fractional momentum loss ($S_{\rm loss}$) as a function of the characteristic path-length ($L$) and the Bjorken energy density times the equilibration time ($\epsilon_{\rm Bj}\tau_{0}$) for heavy-ion collisions at different $\sqrt{s_{\rm NN}}$ is presented. The study has been conducted using inclusive charged particles from intermediate to large transverse momentum...
A typical approach to study the quark gluon plasma produced in heavy ion
collisions is to understand the passage of elementary particles through it. As
electroweak bosons such as photons and Z bosons do not participate in the
strong interaction, their correlation with jets within the same event is a
clean probe of the medium-induced energy loss of jets. With high statistics
PbPb and pp...
As was pointed out long ago by Mueller and Tang, the BFKL hard Pomeron, at finite momentum transfer, can be investigated at hadron colliders by looking for the exclusive processes where the only observed radiation are two jets detected far apart in rapidity. The absence of any additional emission over a large rapidity region suggests that the color-singlet exchange contributes substantially to...
