21. Λ/K0s Associated with a Jet in Central Pb–Pb Collisions at √sNN = 2.76 TeV Measured with the ALICE Detector
Abstract : In high energy heavy ion collisions, the QCD matter undergoes a phase transition to a hot and dense strongly coupled Quark Gluon Plasma, where quarks and gluons are deconfined in a volume of nuclear dimensions. At intermediate pT, 2 < p T < 8 GeV/c, a decoupling from pure hydrodynamical flow is observed, most noticeable in central collisions, demonstrated by the peak in the ratio of baryons to mesons, e.

22. R-hadron Searches and Charged Pion Spectra at High Transverse Momentum in Proton-Proton Collisions at the LHC using the ALICE Detector
Abstract : With the start-up of the Large Hadron Collider (LHC), a new energy regime has opened up. The Standard Model (SM) can be ``rediscovered'' and new theories can be tested. ALICE, the dedicated heavy-ion experiment at LHC, will also record proton-proton (pp) collisions. READ MORE

23. Hadronic Interactions at High and Low Energies
Abstract : In the past, development of the PYTHIA event generator has mainly concentrated on the physics of proton–proton collisions at high energies, as this is the most important case to modern high energy physics experiments. However, there are situations where more generic beam configurations are relevant. READ MORE

24. Identifying charged hadrons on the relativistic rise using the ALICE TPC at LHC
Abstract : The chain from hadron collisions to the physics results requires several important links. First the outcome of the collision is measured by the detectors. Then, the signal from the detector is processed and transformed into information relevant for the study of the physics processes. READ MORE

25. Search for doubly charged Higgs bosons in multi-lepton final states with the ATLAS detector
Abstract : Standard Model events with prompt, isolated, same-charge high-pT leptons are rare, and therefore events with such final states provide a powerful signature towards new discoveries. This thesis presents two searches for doubly charged Higgs bosons decaying into same-charge lepton pairs using proton–proton collision data recorded by the ATLAS detector at the LHC. READ MORE
