Dense and Strange Hadronic Matter
Prof. Laura Fabbietti
Research Field
We are working mainly on strange things, which sounds maybe odd but it refers simply to particles containing a strange quark.
Why is the study of mesons and baryons with a strange content relevant for the human kind? One of the pioneering ideas behind this study was the hypothesis that neutron stars might have a condensate of strange particles in their core. Astronomers look at neutron stars and determine their mass and radii, we collide nuclei in the laboratory and try to produce high density environments, to measure there strange particles and help theoreticians in constraining models for neutron stars... among other things.

- Antimatter Annihilations in the Laboratory
Our group at the Technische Universität München (TUM) (https://www.denseandstrange.ph.tum.de/) studies the properties of hadronic interactions and their implications for astro-particle physics by means of accelerator experiments. The studies are connected to indirect searches for Dark Matter annihilation or decay products, such as stable Standard Model (anti-)particles in final state: p, anti-p, e+, e-, d, anti-d and others. These searches are currently being performed by several satellite- or balloon-based experiments. In particular, low-energy anti-deuterons are very promising probe for such searches, since cosmic ray-induced background is expected to be low. However, these studies suffer from the lack of our poor current knowledge of inelastic interaction cross-sections of anti-deuterons with matter, which are needed for precise calculation of primary and secondary anti-deuteron fluxes expected near the Earth.
The goal of the here advertised project is to study the inelastic interaction of (anti-)deuterons with matter using the ALICE detector at the CERN LHC. In ultra-relativistic collisions at the LHC, (anti-)deuterons are produced in large amounts, which, together with unique ALICE tracking and PID capabilities, allows one to investigate the inelastic interaction of (anti-)deuterons with the detector material. The idea of the project is to use the ALICE TPC and TOF sub-detectors for (anti-)deuteron identification and the material of the TRD sub-detector located between them as a passive absorption target. As a result, an effective anti-d + A inelastic interaction cross-section can be calculated, where A represents the properties of an averaged TRD material element.

- Exploring the properties of Quark-Gluon Plasma with anisotropic flow measurements at the Large Hadron Collider
The matter produced in ultra-relativistic heavy-ion collisions resembles theQuark-Gluon Plasma (QGP), which is an extreme state of nuclear matterconsisting of deconfined quarks and gluons. Such a state existed in the earlyUniverse, just a few microseconds after the Big Bang. Its properties canbe experimentally accessed by measuring the azimuthal anisotropies in themomentum distribution of produced particles in heavy-ion collisions—forinstance, in lead-lead collisions reconstructed with the ALICE detector atCERN’s Large Hadron Collider (LHC).Of particular interest in this context is anisotropic flow phenomenon,which is an observable directly sensitive to the properties of QGP. In thisproject, we introduce the basics of anisotropic flow and corresponding anal-yses techniques, and we guide a student throughout all steps needed for itsfinal measurement, in the large-scale LHC datasets distributed on Grid.We start a project by briefly introducing a theoretical framework withinwhich an anisotropic flow phenomenon can be defined and quantified. Next,we introduce sophisticated multi-particle correlation techniques, which weredeveloped recently by experimentalists particularly for anisotropic flow mea-surements. We go in detail through the practical implementation of multi-particle correlations (students are expected at this point to perform somesimple analytic calculations, and to learn and perform programming tasksboth in ROOT and AliROOT. ROOT is the object-oriented analysis frame-work written in C++ programming language, and it is used at the moment asa default software in high-energy physics by all major collaborations world-wide, while AliROOT is the more specific analysis framework developed byALICE Collaboration, and which is based on ROOT.)We wind up the project by letting the student do an independent ani-sotropic flow analysis with his/her own newly developed code in AliROOT,utilizing multi-particle correlation techniques, over real heavy-ion collisionsrecorded at LHC, and stored on Grid.The project is open both to Bachelor and Master students.

- Hyperon-Korrelationen mit LHC Daten: ein Schlüssel zu den Eigenschaften von Neutron-Sternen
Neutronsterne sind die dichteste Objekte in unserem Universum und keiner weiss noch was drin ist.
Es könnte nur Neutronen geben oder andere Hadronen, wie Hyperonen ( Baryonen mit mindest einem Strange quark), oder man könnte sogar ein Quark GLuon Plasma dadrin finden.
Diese sehr untescheidlichen Szenarios kann man nur testen, wenn man die Wechselwirkungen zwischen den verschiedenen Konstituenten bestimmt. Wechselwirkungen zwischen Hyperonen sind bisher nicht genau bekannt und das Themas diese Arbeit ist die Untersuchung der Korrelationen zwischen Lambda und Xi HYperonen.
Es werden Daten benutzt, die von mit dem ALICE Detektor am LHC aufgenommen worden sind und die Aufgabe besteht eine neue Analyse zu entwickeln, die uns erlauben wird verschiedene theoretische Vorhersage zu testen.
Die Analyse wird in C++ geschrieben und es werden auch Simulationen durchgeführt werden.
Eine Vorkenntis in C++ is willkommen aber nicht notwendig. Experte im Bereiche der Analyse und Simulationen werden die direkte Betreuung der Arbeit übernehmen.
Die Kandidatin/ der kandidat werden die Möglichkeit haben, in Kontakt mit der internationalen ALICE COllaboration am CERN zu kommen.
