Angular correlations as an experimental tool to probe hadron collisions

Malgorzata Janik - Warszaw University of Technology

Abstract

Two-particle angular correlations are a robust tool which allows the exploration of the underlying physics phenomena of particle production in collisions of both protons and heavy ions by studying the distributions of angles in Delta(eta)-Delta(phi) space (where Delta(eta) is the pseudorapidity difference and Delta(phi) is the azimuthal angle difference between two particles). These correlations open up the possibility to study a number of mechanisms simultaneously. Many phenomena, including mini-jets, elliptic flow, Bose-Einstein correlations, resonance decays, conservation laws, are sources of correlations. Each one produces a characteristic distribution in Delta(eta)-Delta(phi) space and contributes to the final shape of the correlation function. In this talk I will present an overview of two-particle angular correlation measurements and their interpretation from pp, pA and AA collisions, including latest results from LHC experiments.

Controversial Phenomena in Collider Data and the Five Sigma Criterion in high-energy physics

Tommaso Dorigo - INFN Padova

Abstract

Extraordinary claims require extraordinary evidence. The p < 0.000029% criterion used in high-energy and astroparticle physics does not appear adequate to cover all experimental situations. The seminar will start with a short history of anomalies found in HEP data and their resolution, and then focus on the statistical problem of defining a proper discovery level for new phenomena and on the non-trivial issues it entails.

Hadrons interaction and consequences for neutron stars

Laura Fabbietti - TU München

Abstract

Many physicists would like to know what is inside neutron stars (NS). Others would be already very happy if they could understand how two and three baryons interact with better accuracy than available today. The two things are intertwined since the two and three body hadron interaction determines the equation of state, hence how pressure and energy depend on density, for every hadron system. Different hypotheses can be made about the content of NS. The scenarios vary from pure dense neutron matter, to mixtures of neutrons and strange hadrons up to quark matter. Each hypothesis, provided that the interaction among the constituents is well known, leads to an equation of state and to a precise mass to radius relationship for the NS. This way, observations of masses and radii for NS can test different hypotheses. A new method is proposed to exploit particle production at accelerator experiments to substitute scattering experiments among different hadron species. This idea can also open up the possibility of studying three body interactions among hadrons. First results from the HADES and ALICE collaborations, two experiments at very different beam energies, will be shown and the potential of the method will be discussed.
