Το ψήσιμο ενός κέικ είναι σημαντικά ευκολότερο από το ψήσιμο ενός σύμπαντος: όλα τα συστατικά αποτελούνται από συνηθισμένη ύλη και είναι άμεσα διαθέσιμα· ο χρόνος προετοιμασίας είναι πολύ μικρότερος και μπορείτε να ξεκινήσετε τη συνταγή σε θερμοκρασία δωματίου.

Baking a cake is considerably easier than baking a universe: all ingredients are made of ordinary matter and are readily available; the preparation time is much shorter, and you can start the recipe at room temperature.

Gâteau de l’UNIVERS

Reference: Poster-2024-1192
Note: Recette de gâteau de l’UNIVERS
Created: 2024. -1 p
Creator(s): Novakova, Lucie

Il est bien plus simple de confectionner un gâteau que de confectionner un univers : tous les ingrédients nécessaires pour préparer un gâteau sont faits de matière ordinaire et se trouvent facilement, la préparation prend beaucoup moins de temps et s’effectue initialement à température ambiante.

gFEX - A Novel Feature Extractor for the ATLAS Level-1 Calorimeter Trigger
Reference: Poster-2024-1190
Keywords:  Level 1 Trigger  gFEX
Created: 2024. -1 p
Creator(s): Omar, Rabia

Run 3 of the Large Hadron Collider (LHC) collides protons at an unprecedented energy of 13.6 TeV every 25 ns. The high luminosity conditions result in a high pile-up background which is challenging for the ATLAS trigger to contend with. The L1 trigger system operates at fixed latency, receiving inputs at a rate of 40 MHz and an output rate limited to 100 kHz. To maintain Run 2 acceptance rate and improve sensitivity to interesting physics processes, the trigger systems underwent major Phase-I upgrades. The L1 calorimeter trigger upgrades included the addition of three FPGA-based feature extractors that utilise the increased granularity of the Run3 liquid argon calorimeter to efficiently trigger electromagnetic and hadronic objects. The Global Feature Extractor (gFEX) receives the complete calorimeter data at a granularity (0.2 η x 0.2 ɸ towers) and implements novel algorithms to study physics objects - large radius jets, missing transverse energy (MET) and total transverse energy. Global trigger objects (TOBs) are computed by gFEX with an algorithm called Jets-Without-Jets (JwoJ) while the large R jets are computed by a seedless cone clustering algorithm. This is effective in triggering physics processes with highly energetic boosted objects in the hadronic decays of high momentum Higgs, bosons, top quarks, and exotic particles. In addition, gFEX implements event-by-event pileup suppression for these jets using baseline subtraction techniques developed for offline analyses. The pileup suppression coupled with novel algorithms allows for efficient triggering of large R jets and global trigger objects with good background rejection.

Laboratory realization of relativistic pair-plasma beams: an experimental platform at HiRadMat - CERN
Reference: Poster-2024-1189
Keywords:  CERN HiRadMat
Created: 2024. -1 p
Creator(s): Stergiou, Vasiliki

Relativistic outflows enriched with electron-positron pair plasma can be found in various highly energetic astrophysical environments, e.g. around active galactic nuclei, black holes or in the jets of gamma ray bursts. Plasma instabilities associated with such pair-dominated outflows play an important role in explaining their energy dissipation and the radiative signatures we observe from these objects on Earth. In our last experiment, HRMT62 [1], inaugurating a newly developed experimental platform for such studies at the HiRadMat facility of CERN [2,3], high intensity, high density, ultra-relativistic, quasi-neutral electron- positron pair beam production was achieved, opening up the possibility to study the microphysics of such pair plasmas via experimental means. In the follow-up experiment, HRMT64, modifications including a secondary target and a magnetic collimating setup will be introduced in order to study the emergence of magnetic fields associated with the growth of filamentation instabilities as collimated relativistic pair-plasma beams propagate through ambient plasma; an analogue for the propagation of astrophysical pair jets through intergalactic medium.

Flow and correlation measurements at LHCb
Reference: Poster-2024-1188
Created: 2024. -1 p
Creator(s): Lian, Zhengchen; Wang, Jianqiao

Particle correlations are powerful tools for studying quantum chromodynamics in hadron collisions. In heavy-ion collisions, azimuthal angular correlations probe collective phenomena in hot, dense, nuclear media, such as QGP. Angular correlations in small collision systems could point to QGP production or potential initial-state correlations. The LHCb experiment has the unique ability to study particle correlations in high-energy hadron collisions at forward rapidity, complementing the results from other experiments. In this contribution, recent results on collective flow from the LHCb experiment will be discussed

Exploring hadronization with heavy-flavor jets with LHCb
Reference: Poster-2024-1187
Created: 2024. -1 p
Creator(s): Durham, John Matthew

Understanding the nonperturbative process of hadronization is a persistent goal in experimental studies of QCD. Since heavy quark production is suppressed at the hadronization scale, heavy-flavor hadrons offer a high-precision probe of the connection between theoretical calculations and experimental final states. Jets containing different flavors of these heavy hadrons, reconstructed across a broad range of jet transverse momentum, explore the dependence of local hadronic formation at different partonic mass scales with distinct final states. Furthermore, quarkonia production in jets explores the intersection between the parton shower, where gluons split into heavy quark-antiquark pairs, and the production of closed heavy-flavor hadrons. Jet substructure can also be used to probe the formation of exotic hadrons, whose structure is still not well understood. This talk presents recent studies of hadronization using heavy-flavor jets detected with the LHCb detector. These studies include inclusive hadron production in heavy-flavor jets, as well as quarkonia and tetraquark production in jets. Results are compared to various models of hadronization, providing strong new constraints on theoretical predictions of confinement in jets.
