The discovery of a new boson compatible with the expectations for the Standard Model Higgs propelled LHC physics into a new era. Studying the properties and couplings of the newly discovered particle immediately became a goal of primary importance. The di-tau final state currently provides the only means of probing the coupling of the Higgs to…

Neutrino masses provide a direct window into Physics Beyond the Standard Model. It is an open question whether massive neutrinos are Majorana fermions or Dirac fermions. Majorana neutrinos, which violate lepton number conservation, offer an intriguing mechanism for generating small neutrino masses. The most practical experimental approach for…

ALICE (A Large Ion Collider Experiment) is a dedicated heavy ion experiment at Large Hadron Collider (LHC) at the European Center for Nuclear Research (CERN). The goal of the experiment is to study strongly interacting matter at extreme energy densities (QCD thermodynamics). Statistical QCD predicts that, at sufficiently high densities, there…

Experiments at the Large Hadron Collider (LHC) have discovered a new particle that appears to be the long-sought Higgs Boson. To confirm that this particle has all the properties predicted by the Standard Model of Particle Physics, its couplings to fermions must be observed directly. The most common Higgs decay is to pairs of bottom quarks, but…

The possibilities for future directions of precision Higgs physics from the current results and extrapolations at the LHC to a wide range of potential upgrades and new collider facilities are presented and compared. The strategies for producing simulation results and the benchmarks for physics and detector performances are discussed. This…

We present searches in the top-quark, dark matter and BSM Higgs sectors at the CDF and ATLAS experiments. We present a search for fourth generation quarks at the ATLAS detector using a novel W identification method. We search for a new particle resonance that might explain the CDF observed top-quark asymmetry at CDF and ATLAS. We also describe a…
