• #### 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 ...
• #### 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. ...
• #### 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 ...
• #### 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 ...
