6. A Study of Number-Ratio Fluctuations in Gold-Gold Interactions at sqrt(s_NN)=200 GeV
Abstract : The properties of the basic building blocks of nuclear matter, the quarks, and their interactions are not known in detail, largely because observations are complicated by the confinement of quarks in composite particles. New insights can be gained from the study of nuclear matter in a deconfined phase, like the form of matter that the Universe consited of early in its evolution according to the Big Bang theory.

7. Properties of Hadronization in e+e- -Annihilation
Abstract : Possible effects from colour interferences in strong interactions are discussed and investigated, and possible experimental signals in e+e- --> hadrons and e+e- --> W+W- --> hadrons are suggested. The observability of the signals depend on the relative probabilities of the occurrence of interferences, and can provide a measurement of the probabilities. READ MORE

8. Calibration of b-tagging efficiency and search for Dark Matter production in association with heavy flavour quarks with the ATLAS experiment
Abstract : The Large Hadron Collider (LHC) is the most powerful and complex particle accelerator ever built. The ATLAS detector is a general-purpose particle detector at the LHC, designed to cover a wide range of physics measurements. READ MORE

9. Pair production of Higgs bosons in the final state with bottom quarks and τ leptons in the ATLAS experiment : Search results using LHC Run 2 data and prospect studies at the HL-LHC
Abstract : After the discovery of the Higgs boson, the ultimate test of the electroweak symmetry breaking and the Standard Model (SM) of particle physics is to establish evidence of Higgs boson self-coupling, which can be achieved by searching for pair production of Higgs bosons. In addition, many theories beyond the SM predict heavy resonances that could decay into pairs of Higgs bosons. READ MORE

10. Production of strangeness in partonic interactions at the LHC
Abstract : The strong interaction is responsible for nearly all observable baryonic matter in the Universe. Quantum Chromodynamics, which describes interactions between quarks and gluons, however, cannot be solved analytically in the non-perturbative regime, involving low momentum transfers. READ MORE
