Title: International Particle Physics Masterclasses with LHC data
Author: Foka Panagiota
Subject: Physics
Description: The International Particle Physics Masterclasses is an educational activity developed by the International Particle Physics Outreach Group with the aim to bring the excitement of cutting-edge particle-physics research into the classroom. Since 2005, every year, thousands of pupils in many countries all over the world become “scientists for a day” in research centres or universities close to their schools as they are introduced to the mysteries of particle physics. In 2012, 10 000 students from 148 institutions in 31 countries took part in this popular event over a month period. 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 students perform measurements on real data from particle-physics experiments themselves. The last two years LHC data from the ALICE, ATLAS and CMS experiments were used. A overview of the performed measurements and the employed methodology is presented....

Title: Quantum mechanical localization effects for Bose-Einstein correlations
Author: Wiedemann, Urs Achim; Foka, Panagiota; Kalechofsky, Hal; Martin, Michel; Slotta, C.; Zhang, Q.H.
Date: 1997
Description: For a set of N identical massive boson wave packets with optimal initial quantum mechanical localization, we calculate the Hanbury-Brown–Twiss (HBT) two-particle correlation function. Our result provides an algorithm for calculating one-particle spectra and two-particle correlations from an arbitrary phase space occupation (qi,pi,ti)i=1,N as, e.g., returned by event generators. It is a microscopic derivation of the result of the coherent state formalism, providing explicit finite multiplicity corrections. Both the one- and two-particle spectra depend explicitly on the initial wave packet width σ which parametrizes the quantum mechanical wave packet localization. They provide upper and lower bounds which suggest that a realistic value for σ has the order of the Compton wavelength.

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 last three years data from the ALICE experiment at LHC were used. The performed measurement “strangeness enhancement” and the employed methodology are presented.

Title: Azimuthal anisotropy in S + Au reactions at 200 A GeV

Description: Azimuthal correlations of photons produced at mid-rapidity in 200 A GeV S + Au collisions have been studied using a preshower photon multiplicity detector in the WA93 experiment. The Fourier expansion method has been employd to estimate the event plane via the anisotropy of the event as a function of centrality. The event plane correlation technique has been used to determine the true event anisotropy, beyond the anisotropy which arises due to finite multiplicity. The VENUS event generator with rescattering and proper simulation of the detector response can explain only a portion of the observed anisotropy. The residual anisotropy is found to be of the order of 5% for semi-central collisions. This suggests that directed collective flow of the produced particles is present at SPS energies.
