Young Scientists' Session: High energy particle physics
- Andrzej Konrad Siodmok (Polish Academy of Sciences (PL))
Abstract: Space-time evolution of spin polarization within the framework of hydrodynamics with spin based on de Groot - van Leeuwen - van Weert forms of energy-momentum and spin tensors is studied. Due to the non-boost invariant flow in the system the spin polarization components couple to each other implying some effects on the spin polarization observables. We study transverse-momentum and...
As a result of hadronization, the partons (quarks and gluons) are being observed via objects called jets which represent energy deposits in clustered calorimeters with associated jet reconstruction algorithm. This study investigates the determination of the initial parton from which the jet evolved based on five variables called angularities. Having a discriminant on an event-by-event basis...
High energy proton-proton and proton-lead collisions may proceed via double-parton scattering. In addition, soft interactions accompany any hard process. To describe these processes, Pythia parameters are revised and constantly tuned to match Run 2 LHC data and to make better predictions that would fit the astrophysics data. In this presentation, the recent LHCb results on double-parton...
Analyses of D meson yields as functions of decay time provide access to fundamental standard model parameters and probe natural non-SM scales at 10-100 TeV energies. Outstanding vertexing performances are key enablers of this program. We prove the capabilities of the Belle II detector by measuring the lifetimes of the D0 and D+ mesons. The results are the most precise to date, owing to a...
Large Hadron Collider- beauty (LHCb) is one of the four large experiments operating currently at Large Hadron Collider(LHC) it is designed to study New Physics phenomena in the heavy flavor quarks sector and perform precise measurements of CP symmetry violation in beauty and charm quarks sector. At present, the detector is undergoing a major upgrade with respect to its original design. In...
The MUonE experiment planned to be operating at the SPS accelerator in 2021-2022 (pilot run) and 2023-26 provides a great potential to search for New Physics in the sector o of the anomalous muon magnetic moment a_μ. The discrepancy between the most accurate determination of a_μ and the Standard Model predictions is about 4 standard deviations, and an analogous improvement is required in...
At extremely high temperatures and densities, hadronic matter undergoes a phase transition to a state of deconfined quarks and gluons known as quark-gluon plasma (QGP). It is believed that our universe had been in such deconfined state just after the big bang when the temperature was of the order of several thousand billion degrees. Such state of matter might be also present in the inner...
