• #### Cone-Size Dependence of Jet Suppression in Heavy-Ion Collisions ﻿

(Journal article; Peer reviewed, 2021)
The strong suppression of high-pT jets in heavy-ion collisions is a result of elastic and inelastic energy loss suffered by the jet multiprong collection of color charges that are resolved by medium interactions. Hence, ...
• #### Deep learning jet modifications in heavy-ion collisions ﻿

(Journal article; Peer reviewed, 2021)
Jet interactions in a hot QCD medium created in heavy-ion collisions are conventionally assessed by measuring the modification of the distributions of jet observables with respect to the proton-proton baseline. However, ...
• #### Dynamical grooming of QCD jets ﻿

(Journal article; Peer reviewed, 2020-02-06)
We propose a new class of infrared-collinear and Sudakov safe observables with an associated jet grooming technique that removes dynamically soft and large angle branches. It is based on identifying the hardest branch in ...
• #### Higher-order corrections to heavy-quark jet quenching ﻿

(Peer reviewed; Journal article, 2019-07-03)
We calculate higher-order corrections to the quenching factor of heavy-quark jets due to hard, in-medium splittings in the framework of the BDMPS-Z formalism. These corrections turn out to be sensitive to a single mass ...
• #### Improved opacity expansion for medium-induced parton splitting ﻿

(Journal article; Peer reviewed, 2020-06-30)
We present a new expansion scheme to compute the rate for parton splittings in dense and finite QCD media. In contrast to the standard opacity expansion, our expansion is performed around the harmonic oscillator whose ...
• #### Jet quenching and effects of non-Gaussian transverse-momentum broadening on dijet observables ﻿

(Journal article, 2020)
We study, at a qualitative level, production of jet pairs in ultrarelativistic nuclear collisions. We propose a new framework for combining kT factorization and a formalism for in-medium propagation of jet particles that ...
• #### The Large Hadron–Electron Collider at the HL-LHC ﻿

(Journal article; Peer reviewed, 2021)
The Large Hadron–Electron Collider (LHeC) is designed to move the field of deep inelastic scattering (DIS) to the energy and intensity frontier of particle physics. Exploiting energy-recovery technology, it collides a ...
• #### Mapping collinear in-medium parton splittings ﻿

(Journal article; Peer reviewed, 2020-01-07)
We map the spectrum of 1→2 parton splittings inside a medium characterized by a transport coefficient q^ onto the kinematical Lund plane, taking into account the finite formation time of the process. We discuss the distinct ...
• #### Medium-induced cascade in expanding media ﻿

(Journal article; Peer reviewed, 2020)
Detailed insight into the interplay between parton energy loss and the way deconfined medium created in heavy-ion collisions expands is of great importance for improving the understanding of the jet quenching phenomenon. ...
• #### Medium-induced radiative kernel with the Improved Opacity Expansion ﻿

(Journal article; Peer reviewed, 2021)
We calculate the fully differential medium-induced radiative spectrum at next-to-leading order (NLO) accuracy within the Improved Opacity Expansion (IOE) framework. This scheme allows us to gain analytical control of the ...
• #### Midrapidity antiproton-to-proton ratio in pp collisons root s=0.9 and 7 TeV measured by the ALICE experiment ﻿

(Journal article, 2010)
The ratio of the yields of antiprotons to protons in pp collisions has been measured by the ALICE experiment at root s = 0.9 and 7 TeV during the initial running periods of the Large Hadron Collider. The measurement covers ...
• #### Online data compression in the ALICE O$^2$ facility ﻿

(Peer reviewed; Journal article, 2017)
The ALICE Collaboration and the ALICE O2 project have carried out detailed studies for a new online computing facility planned to be deployed for Run 3 of the Large Hadron Collider (LHC) at CERN. Some of the main aspects ...
• #### Parton energy loss: new theoretical progress ﻿

(Journal article; Peer reviewed, 2021)
The physics of jet quenching combines the dynamics of the QCD parton shower with bremsstrahlung radiation and decoherence processes induced by interactions with an underlying medium. Here we present a brief overview of the ...
• #### Quenching effects in the cumulative jet spectrum ﻿

(Journal article; Peer reviewed, 2021)
The steeply falling jet spectrum induces a bias on the medium modifications of jet observables in heavy-ion collisions. To explore this effect, we develop a novel analytic framework to study the quenched jet spectrum and ...
• #### Revisiting transverse momentum broadening in dense QCD media ﻿

(Journal article; Peer reviewed, 2021)
We reconsider the problem of transverse momentum broadening of a highly energetic parton suffering multiple scatterings in dense colored media, such as the thermal quark-gluon plasma or large nuclei. In the framework of ...
• #### Tagging boosted hadronic objects with dynamical grooming ﻿

(Journal article; Peer reviewed, 2020)
We evaluate the phenomenological applicability of the dynamical grooming technique, introduced by Y. Mehtar-Tani, A. Soto-Ontoso, and K. Tywoniuk [Phys. Rev. D 101, 034004 (2020)], to boosted W and top tagging at LHC ...
• #### Wilson line correlators beyond the large-Nc ﻿

(Journal article; Peer reviewed, 2021)
We study hard 1 → 2 final-state parton splittings in the medium, and put special emphasis on calculating the Wilson line correlators that appear in these calculations. As partons go through the medium their color continuously ...
