Jet substructure is a powerful tool to probe the perturbative regime of jet evolution in proton-proton and heavy-ion collisions. Over the past few years, a wide variety of substructure observables have been proposed in order to understand specific aspects of jet dynamics in a quark-gluon plasma (QGP).
In this talk, based on [1,2], we will explore the ability of such an observable, called...
Jets in relativistic heavy-ion collisions interact with the quark-gluon plasma (QGP), leading to effects such as a suppression of jet yields and modification of internal jet structure that are used to measure the properties of the QGP. The dependence of jet suppression on the cone size ($R$) and jet $p_{\rm T}$ is a useful observable to disentangle competing energy loss mechanisms with a high...
The LHCb experiment at the LHC is suited for studying how hadrons are formed from scattered quarks and gluons, in energetic proton-proton collisions. The hadronization and fragmentation processes can be studied via measurements such as those involving jet substructure. Equipped with a forward spectrometer, the LHCb experiment achieves an excellent transverse momentum for charged tracks, that...
Quenching features of mullti-partonic cascades in expanding
media are important in understanding the complex phenomena of jet
quenching. We present results for the inclusive jet $R_{AA}$ by
including phenomenologically driven combinations of quark and gluon
fractions inside a jet. In addition, we have also studied the effect of
the nPDF as well as vacuum like emissions on the
jet...
