Charged particles produced in quark and gluon jets in proton-proton collisions

EPJ Web of Conferences, 2011
The study of particle production inside jets makes it possible to address the fragmentation properties of the leading parton depending on its flavour.

Correlations and Event-by-Event Fluctuations in High Multiplicity Events Produced in $^{208}$Pb-$^{208}$Pb Collisions [PDF]

arXiv, 2018
Analysis of high multiplicity events produced in 158A GeV/c $^{208}$Pb-$^{208}$Pb collisions is carried out to study the event-by-event fluctuations. The findings reveal that the method of scaled factorial moments can be used to identify the events having densely populated narrow phase space bins.

Unveiling CP property of top-Higgs coupling with graph neural networks at the LHC

Physics Letters B, 2020
The top-Higgs coupling plays an important role in particle physics and cosmology. The precision measurements of this coupling can provide an insight to new physics beyond the Standard Model. In this paper, we propose to use Message Passing Neural Network

Underlying-event studies with strange hadrons in pp collisions at $$\sqrt{s} = 13$$ s = 13 TeV with the ATLAS detector

European Physical Journal C: Particles and Fields
Properties of the underlying-event in pp interactions are investigated primarily via the strange hadrons $$K_{S}^{0}$$ K S 0 , $$\Lambda $$ Λ and $$\bar{\Lambda }$$ Λ ¯ , as reconstructed using the ATLAS detector at the LHC in minimum-bias pp collision ...

Event by event fluctuations of the source shape: implications for the Levy shape, and Event Shape Sorting [PDF]

arXiv, 2018
In the first part of this contribution we show that the Levy stable shape of the correlation function can be caused by averaging of the measured correlation functions over a large number of events. In the second part it is demonstrated how a sample of events sorted by Event Shape Sorting technique exhibits different azimuthal dependence of correlation ...

Event-by-event fluctuations in heavy ion collisions [PDF]

Acta Phys.Polon. B33 (2002) 1495-1504, 2002
We discuss the physics underlying event-by-event fluctuations in relativistic heavy ion collisions. We will argue that the fluctuations of the ratio of positively over negatively charged particles may serve as a unique signature for the Quark Gluon Plasma.

Neural Networks

EPJ Web of Conferences, 2010
This course presents an overview of the concepts of the neural networks and their aplication in the framework of High energy physics analyses. After a brief introduction on the concept of neural networks, the concept is explained in the frame of neuro ...
