Description of the research topic:
The NA61 experiment is a large phase space coverage fixed target hadron spectrometer experiment at
the CERN SPS accelerator, optimized for the study of hadron-nucleus and nucleus-nucleus collisions at
the beam momentum range of 13–400 GeV/c per elementary charge, i.e. at the ultrarelativistic regime.
The nucleus-nucleus collision data are used primarily for heavy-ion physics: these measurements help
gaining experimental information on particular phenomena of the strong interaction. Hadron-nucleus
data provide a very important reference in order to interpret the nucleus-nucleus results in a relatively
model independent way. The hadron-nucleus data become particularly valuable if they are
differentiated agains collision centrality. The Hungarian NA61 group developed a specific detector for
this purpose, the Low Momentum Particle Detector (LMPD), which can be used to indirectly
characterize event-by-event the centrality in hadron-nucleus collisions. One of the aims of the present
doctoral project is the analysis of the already recorded large statistics proton-lead data, tagged with
LMPD information, from the point of view of identified single particle hadron poduction spectra, also
differentiated against event centrality. These experimental results, in combination with the already
available RHIC results at 10-fold higher energies, help to understand the behavior of the strong
interaction at the intermediary SPS–RHIC energy range. The hadron-nucleus spectra are, however also
useful for experimental programs beyond heavy-ion physics, primarily for the neutrino beam based
neutrino oscillation experiments (DUNE). During the doctoral project we intend to develop a new
tracking detector loosely based on the LMPD design, but also involving so-called micro-pattern
gaseous detector technologies, using which data one can obtain a better tracking accuracy in the closeto-target region.
