Faculty of mathematics and physics of the Charles university (Prague, Czechia) is accepting applications to PhD programmes (to start studying in February 2024). Details on the requirements and the procedure can be found in the faculty admissions page. (apply before November 30). Practical info on living in Prague can be found here.
The AMBER (CERN) experiment group at the faculty is offering a PhD thesis topic and a supplementary scholarship to one applicant to the particle and nuclear physics programme , who is interested in experimental physics of AMBER. The scholarship would add to the default one given by the faculty to provide in total at least 25.000 CZK (about 1.000 EUR) per month and can be guaranteed for 2 years. The proposed thesis topic is described below. The study may be conducted in cooperation with one of the AMBER collaboration institutions or with CERN.
Measurement of antiproton production and development of data acquisition and reconstruction tools at AMBER
The thesis topic consists of two parts. Depending on the qualification and interest of the student and needs of the collaboration, one or the other part may be given greater weight.
1. Measurement of the antiproton production cross section in proton-helium or proton-proton interactions
Measurements of the AMS spectrometer include the cosmic antiproton flux AMS, Phys.Rep. 894, 2021. They are expected to be produced dominantly in collisions of high energy proton cosmic rays with the interstellar medium, mostly hydrogen and helium, at rest. The AMBER collaboration CERN- SPSC-2019-022 has collected data on 100-190 GeV protons scattering off a liquid helium target, an experiment with hydrogen target is being proposed as well D. Giordano, PoS ICHEP2022 (2022) 1197. Analysis of these data (together with complementary data from LHCb experiment in TeV domain) will significantly improve the knowledge of the cross section of this conventional antiproton production. That is necessary to assess if the measured flux leaves space for exotic antiproton sources such as dark matter annihilation M. Korsmeier et al., FPhys.Rev.D97 (2018) 103019.
2. Development of trigger-less data acquisition and related tools
Other physics programme of the AMBER collaboration, measurements of the elastic mion-proton scattering and pion- and kaon-induced Drell-Yan process, requires to upgrade the detector readout. Instead of analogue triggering all the data will be acquired and their filtering will take place at higher (software) level, where the events can be partially reconstructed (high- level trigger) M. Zemko et al., PoS ICHEP2022 (2022) 248. The readout (front-end) electronics needs to be adapted to fit this system; new tools for event reconstruction and online monitoring of the data being collected need to be developed as well.Requirements
Master Degree or equivalent
Knowledge of particle (sub-nuclear) physics on Master degree level. Background in hadron physics (parton model etc.) would be appreciated.
Experience with data analysis and computer programming, in the optimal case with ROOT (in C++ or Python) in particular.
English for professional communication and scientific writing.
The applicants interested in the topic shall send a brief CV and motivation letter to Jan Matousek and arrange for a reference letter to be sent to the same address by a relevant referee.
