LIP opens a call for selection of fellows a Research Student Fellowship (BI – Bachelor) for participation in the project “Bridging Theory and Experiment: Collider Phenomenology (II)”, reference CERN/FIS-PAR/0032/2021, funded by FCT/MCTES through national funds (State Budget – OE).

Work plan:

The work plan will be carried out in the context of the activities of the Phenomenology group at LIP, namely in the research connected to the study of jets and its application to the high-energy nuclear collisions produced at the LHC (Large Hadron Collider at CERN, Switzerland). In ultra-relativistic heavy-ion collisions, it is possible to reach extreme conditions of temperature and density that allow to recreate the primordial state of the Universe where the fundamental degrees of freedom of Quantum Chromodynamics (quarks and gluons), are deconfined: the Quark-Gluon Plasma (QGP). The study of this hot and dense medium is at the forefront of the physics research at the most energetic heavy-ion colliders: RHIC (BNL) and the LHC (CERN). Jets - collimated bunches of particles that result from the branching of highly energetic partons — are produced concurrently with the QGP in the collision and thus modified with respect to their `vacuum` counterparts (eg, jets produced in proton-proton collisions). Such modifications, resulting from the interaction between a jet and the QGP, are collectively referred to as "jet quenching” and provide detailed insights into the properties of the QGP. Current theory-to-data comparisons in heavy-ions jet physics primarily rely on the adaptation of widely used Monte Carlo proton-proton event generators, so as to incorporate QGP-induced effects. The accuracy of these tools is thus a critical ingredient in the inference of QGP properties. One of the missing ingredients in these codes are next-to-leading corrections in the matrix element generation. The selected candidate will delve into the differences arising from using a Leading order (LO) or Next-to-leading (NLO) vacuum baseline for jet quenching studies, with a particular focus on jet substructure observables in the ALICE kinematic regime.

Legislation:

The fellowship contract will be established according to the “Regulations for Research Grants of the Foundation for Science and Technology” (https://dre.pt/application/conteudo/127238533) and to the Status of Scientific Research Fellow (Law nº 40/2004, August 18th, and its successive amendments).

Duration:

The fellowship has a maximum duration of 3 months, with a foreseen starting date on May 01, 2024. The fellowship cannot be further renewed.

The working plan will be carried out at LIP-Lisbon and Lip Coimbra under the supervision of Dr. Liliana Apolinário.

Application:

Applicants should submit: a motivation letter and a curriculum vitae (both in English), bachelor’s certificate, including the list of classifications obtained in the different curricular units, and other relevant documents, as a PDF file, by email to ofelia@lip.pt  and natalia@lip.pt .
