Title: Overview of recent femtoscopy measurements with ALICE
Author: Janik, Małgorzata
Contributor: Janik, Małgorzata (pacrepositoryorg)
Subject: Gluons ; Quarks ; Strong Interactions (Field Theory) ; Quark-Gluon Plasma ; Interaction Parameters ; Rangefinding ; Correlation Analysis ; Ionic Collisions
Description: One of the key methods used in the study of the Quark-Gluon Plasma (QGP) is femtoscopy, the technique of measuring short-range two-particle correlations as a function of relative momentum. Traditionally, femtoscopy has been utilized to measure the size of the QGP fireball created in relativistic heavy-ion collisions. However, since it is sensitive to the correlations between the particles in the final state, it has been shown recently that the parameters of the strong interaction can be probed as well. This review includes a broad range of ALICE femtoscopy results, including both traditional and novel measurements of the interaction between particles.

Title: \Delta\eta\Delta\phi\ angular correlations in pp collisions at the LHC registered by the ALICE experiment
Author: Janik, Małgorzata
Contributor: Janik, Małgorzata (pacrepositoryorg)
Subject: Transverse Momentum ; Particle Collisions ; Dependence ; Correlation Analysis
Description: We report on studies of two-particle \Delta\eta\Delta\phi\ angular correlations measured in proton-proton collisions at center of mass energies sqrt{s} = 0.9 TeV, sqrt{s} = 2.76 TeV and sqrt{s} = 7 TeV registered by the ALICE experiment at LHC. We present the dependence of the correlation function on the pair transverse momentum, the multiplicity of the event and the charge combination of particles in the pair. \Delta\eta\Delta\phi correlations are expected to exhibit several structures which arise from different physics mechanisms. The results are also related to the correlations obtained by femtoscopic analysis. We show that the minijet hypothesis for the non-femtoscopic underlying correlation should be taken into account while performing the femtoscopy analysis.

Title: Insight into particle production mechanisms via angular correlations of identified particles measured with ALICE in pp collisions at $$\mathbf{\sqrt{{\textit s}}}=7$$ TeV
Author: Janik, Małgorzata
Contributor: Janik, Małgorzata (pacrepositoryorg)
Subject: Quarks ; Quantum Statistics ; Collisions ; Antiparticles ; Baryons ; Mesons ; Particle Decay ; Quark-Gluon Plasma ; Particle Production ; Fragmentation ; Computer Simulation ; Correlation Analysis ; Conservation Laws
Description: Two-particle correlations as a function of $$\Delta\eta$$ and $$\Delta\varphi$$ are used in all collision systems to study a wide range of physical phenomena. Examples include the collective behavior of the quark-gluon plasma medium, jets, quantum statistics or Coulomb effects, conservation laws, and resonance decays. In this work, measurements of the correlations of identified particles and their antiparticles (for $$\pi$$, K, p, $$\Lambda$$) are reported in pp collisions at $$\sqrt{s}=7$$ TeV at low transverse momenta. The analysis reveals differences in particle production between baryons and mesons. The correlation functions for mesons exhibit the expected peak dominated by effects of mini-jet fragmentation and are reproduced well by general purpose Monte Carlo generators. For baryon pairs where both particles have the same baryon number, a near-side anti-correlation structure is observed instead of a peak; our experimental observation present a challenge to the contemporary models...

Title: ALICE Masterclass on strangeness
Author: Foka Panagiota; Janik Małgorzata
Subject: Physics
Description: An educational activity, the International Particle Physics Masterclasses, was developed by the International Particle Physics Outreach Group with the aim to bring the excitement of cutting-edge particle-physics research into the classroom. Thousands of pupils, every year since 2005, in many countries all over the world, are hosted in research centers or universities close to their schools and become “scientists for a day” as they are introduced to the mysteries of particle physics. The program of a typical day includes lectures that give insight to topics and methods of fundamental research followed by a “hands-on” session where the high-school students perform themselves measurements on real data from particle-physics experiments. The last three years data from the ALICE experiment at LHC were used. The performed measurement “strangeness enhancement” and the employed methodology are presented.

For baryon pairs where both particles have the same baryon number, a near-side anti-correlation structure is observed instead of a peak; our experimental observation present a challenge to the contemporary models (PYTHIA, PHOJET). This effect is further interpreted in the context of baryon production mechanisms in the fragmentation processes. Comment: Proceedings of Strangeness in Quark Matter 2017 Conference

Subject: Language and Literature Studies ; Studies of Literature ; Polish Literature ; Dziady – a Pagan Festival in Honour of Ancestral Spirits ; Rite ; Romanticism ; Culturalsocial Anthropology
Description: The publication presented in the review is an interesting and much-needed research proposal, which combines the discourse of a philologist, an ethnographer, and a cultural anthropologist. This approach is innovative in the literary studies research on this Polish master dramatist; it constitutes a valuable source not only for literary commentators of Mickiewicz’s series but also for Belorussian folklore scholars, or for those investigating the merging of Polish and Belorussian culture. It makes us realize that, among others, by means of his drama, the poet introduced the Belorussian rite of dziady – a pagan festival in honour of ancestral spirits – into Polish culture. The rite is, for the Belorussians, not only a literary picture but still a cultivated, common, and obvious phenomenon. Similarly, the book unravels a fragment of a common cultural sphere; the renewed and repeated dziady rite helps to explain the poet’s masterpiece, though it unravels only one piece of it and fails...
