X2.00001: J. J. Sakurai Prize for Theoretical Particle Physics Lecture: Particle physics after the first LHC results Invited Speaker: Guido Altarelli The LHC results released so far have very much restricted the possible range for the Standard Model Higgs boson mass. Moreover some indications for a signal at a mass around 125 GeV have been found. At the same time, no clear evidence for new physics has emerged from the LHC data. We discuss the impact of these results on our understanding of particle physics. The presently allowed window for the Higgs mass and the negative results for exotic particles are compatible with both the Standard model and its Supersymmetric extensions but imply considerable restrictions and need a substantial amount of fine tuning in all cases. We discuss the options that remain open and the perspectives for the near future. [Preview Abstract] |

X2.00002: J. J. Sakurai Prize for Theoretical Particle Physics Lecture: Some QCD aspects of physics beyond the standard model Invited Speaker: Torbjorn Sjostrand The nature of observable events at the LHC is mainly determined by QCD physics, i.e. strong interactions. The search for new physics obviously implies a desire to go beyond QCD. Nevertheless, also in cases where non-QCD processes are studied, new aspects of QCD physics may enter the back door. We here give three examples: decays with R-parity violation in SUSY, the formation of long-lived R-hadrons in SUSY, and parton showers and hadronization in Hidden Valley scenarios. These three possibilities have been implemented in the general-purpose PYTHIA event generator, so that detailed studies of consequences can be performed. [Preview Abstract] |

X2.00003: J. J. Sakurai Prize for Theoretical Particle Physics Lecture: Improving the precision of high-energy simulation and analysis tools Invited Speaker: Bryan Webber Comparing theoretical predictions with experimental data on particle collisions like those at the Large Hadron Collider is far from straightforward. The predictions usually concern fundamental objects (quarks, gluons, leptons, \ldots) whereas the colliding hadrons are complicated bound states. Furthermore, final states of interest often contain high-energy jets of many hadrons, together with underlying lower-energy hadron production. The jets may come from primary interactions producing energetic quarks and gluons, or from the decays of heavy or highly boosted objects, possibly new forms of matter. I will discuss the development of computer simulations of jet production in hard collisions, and of jet-finding algorithms that aim to reconstruct the fundamental collision and decay dynamics from hadronic final states. In both cases, improvements in the underlying theoretical framework have led to a better description of Standard Model processes at the LHC, and better tools for the discovery of any new processes that may lie within its reach.
