Abstract
We report on the measurement of two-pion correlation functions from pp collisions at root s = 900 GeV performed by the ALICE experiment at the Large Hadron Collider. Our analysis shows an increase of the Hanbury Brown-Twiss radius with increasing event multiplicity, in line with other measurements done in particle- and nuclear collisions. Conversely, the strong decrease of the radius with increasing transverse momentum, as observed at the Relativistic Heavy Ion Collider and at Tevatron, is not manifest in our data.

Systematic properties of the Tsallis distribution: Energy dependence of parameters in high energy p–p collisions

TL;DR: In this article, changes in the transverse momentum distributions with beam energy were studied using the Tsallis distribution as a parameterization, and the dependence of the parameters q, T and the volume were determined as a function of beam energy.

De-Confinement and Clustering of Color Sources in Nuclear Collisions

TL;DR: In this article, a brief introduction of string percolation to the Quantum Chromo Dynamics (QCD) phase diagram is presented, and the behavior of the Polyakov loop close to the critical temperature is studied in terms of the color fields inside the clusters of overlapping strings, which are produced in high energy hadronic collisions.

Influence of Bose-Einstein Statistics on the Antiproton-Proton Annihilation Process

TL;DR: In this paper, a modification of the usual Fermi statistical model is studied, where the transition rate into a given final state is proportional to the probability of finding $N$ free $\ensuremath{\pi}$ mesons in the reaction volume, but express this probability in terms of wave functions symmetrized with respect to particles of like charge.

A New type of interferometer for use in radio astronomy

Abstract: Summary A new type of interferometer for measuring the diameter of discrete radio sources is described and its mathematical theory is given. The principle of the instrument is based upon the correlation between the rectified outputs of two independent receivers at each end of a baseline, and it is shown that the cross-correlation coefficient between these outputs is proportional to the square of the amplitude of the Fourier transform of the intensity distribution across the source. The analysis shows that it should be possible to operate the new instrument with extremely long baselines and that it should be almost unaffected by ionospheric irregularities.
