1. Silicon Tracking and a Search for Long-lived Particles
Abstract : The ATLAS Detector, below the surface of the Swiss-French border, measures the remnants of high-energy proton-proton collisions, accelerated by the Large Hadron Collider (LHC) at CERN. Recently the LHC paused operations, having delivered an integrated luminosity corresponding to 150 fb−1 of data at a centre-of-mass energy of 13 TeV. READ MORE

2. Machine Learning in High-Energy Physics: Displaced Event Detection and Developments in ROOT/TMVA
Abstract : Many proposed extensions to the Standard Model of particle physics predict long-lived particles, which can decay at a significant distance from the primary interaction point. Such events produce displaced vertices with distinct detector signatures when compared to standard model processes. READ MORE

3. Searches for supersymmetric long-lived particles with displaced-vertex signatures and studies of the electronic noise in the Tile Calorimeter at the ATLAS experiment
Abstract : The Standard Model of particle physics is successful at describing nature on the smallest scales, but it has known flaws. These can be remedied by extended theories, such as supersymmetry. A quantum number in the supersymmetry framework is R-parity. This quantity is generally conserved, but can be violated. READ MORE

4. Charged kaon and proton production in B-hadron decays
Abstract : The production of charged kaons and protons in B-hadron decays has been measured in e+e- annihilations at centre-of-mass energies corresponding to the Z0 mass. In total 1.6 million hadronic Z0 decays were analysed, corresponding to about 690000 B-hadron decays. READ MORE

5. Exploring the Merits and Challenges of Hyperon Physics : with PANDA at FAIR
Abstract : Binary hyperon production in antiproton-proton annihilations will be carried out with the PANDA experiment at FAIR, and probes the strong interaction in the non-perturbative regime where the relevant degrees of freedom are unclear. The self-analyzing decays of hyperons provide a straightforward way to study reaction dynamics via the measurement of spin observables. READ MORE
