1. 1. Time for Hyperons : Development of Software Tools for Reconstructing Hyperons at PANDA and HADES

   Författare :Jenny Regina; Karin Schönning; Michael Papenbrock; Pawel Marciniewski; Laura Fabbietti; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hadron physics; Hyperon; Track reconstruction; 4D tracking; Free-streaming data; Kinematic fitting; PANDA; HADES; Fysik med inriktning mot kärnfysik; Physics with specialization in Nuclear Physics;

   Sammanfattning : The PANDA experiment at FAIR offers unique possibilities for performing hyperon physics. The detector will enable the reconstruction of both hyperon and antihyperon, which will be created together in proton-antiproton collisions. This enables investigations of the strong interaction in the non-perturbative regime. LÄS MER

3. 2. Time-Based Reconstruction of Hyperons at PANDA at FAIR

   Författare :Jenny Regina; Karin Schönning; Michael Papenbrock; Pawel Marciniewski; Sophie Grape; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PANDA; FAIR; hyperons; track reconstruction; online; cellular automaton; 4D tracking; Physics with specialization in Nuclear Physics; Fysik med inriktning mot kärnfysik;

   Sammanfattning : The PANDA (anti-Proton ANnihilation at DArmstadt) experiment at the future FAIR (Facility for Anti-proton and Ion Research) offers unique possibilities for performing hyperon physics.The almost full 4π coverage of the detector will enable the reconstruction of both hyperon and antihyperon which will be created together in proton-antiproton collisions.

4. 3. Λ-Λ hyperons: the road to estimate the production cross-section in protonproton collisions

   Författare :Gandharva Appagere; Maria Doncel Monasterio; Per-Erik Tegnér; Michael Papenbrock; Andreas Heinz; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hyperons; multi-strangeness; neutron-stars; cross-section; Lambda-lambda; Physics; fysik;

   Sammanfattning : In this study, we analyse the $\Lambda$-$\Lambda$ hyperon channel in proton-proton scattering, $pp \mapsto \Lambda\Lambda + K^+K^+, \,\,\Lambda\mapsto p+\pi^-$, with a proton beam energy of $4.5$ GeV using the High Acceptance Di-Electron Spectrometer (HADES) at GSI. LÄS MER

5. 4. Towards Realistic Hyperon Reconstruction in PANDA : From Tracking with Machine Learning to Interactions with Residual Gas

   Författare :Adeel Akram; Karin Schönning; Michael Papenbrock; Carl Nettelblad; Andreas Salzburger; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hyperons; Clusterjet Target; Tracking; Graph Neural Networks; Deep Learning; Physics with specialization in Nuclear Physics; Fysik med inriktning mot kärnfysik;

   Sammanfattning : The PANDA (anti-Proton ANnihilation at DArmstadt) experiment at FAIR (Facility for Anti-proton and Ion Research) aims to study strong interactions in the confinement domain. In PANDA, a continuous beam of anti-protons will impinge on a fixed hydrogen target inside the High Energy Storage Ring (HESR), a feature intended to attain high interaction rates for various physics studies e.

7. 5. Electromagnetic and Spin Properties of Hyperons

   Författare :Elisabetta Perotti; Stefan Leupold; Luis Alvarez Ruso; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electromagnetic form factors; hyperon physics; dispersion relations; QCD; chiral perturbation theory; CP violation; Fysik; Physics;

   Sammanfattning : The study of hyperons improves our understanding of nature in multiple ways. The intrinsic properties of hadrons are not fully understood at a fundamental level. Hence, the electromagnetic properties of hyperons provide complementary information to that of the nucleon and therefore allow for a broader investigation of the structure of matter. LÄS MER
