H6.00001: Silicon detectors and their impact on hadron collider physics Invited Speaker: Silicon detectors are playing a critical role in extracting physics from the complex collisions at hadron colliders. They have been essential for the discovery of the top quark, searches for the standard model Higgs, and the determination of $B_{s }$mixing. I will present examples of the physics reach provided by the precision tracking and vertexing allowed by silicon detectors. I will also discuss the challenges presented by the construction of large silicon trackers for the Tevatron and LHC and the importance of pixel detectors for the LHC experiments. [Preview Abstract] |

H6.00002: Quark Mixing, Neutrino Mixing, Charged Lepton non-Mixing Invited Speaker: The mixing of flavor and mass eigenstates in the quark sector is by now well-known and well-measured through the CKM matrix. We also know that the neutrino flavor and mass eigenstates mix (but with a strikingly different mixing pattern) though the MNS matrix. The puzzle is not so much why these mixings occur, but rather why the charged leptons apparently do not mix. Despite many sensitive searches, flavor mixing of the charged leptons has never been observed. New experiments will push these searches to unprecedented levels. Perhaps charged lepton mixing will finally be observed, perhaps not. In either case the results will shed light on the nature of leptons and the existence and nature of Supersymmetry.

H6.00003: The MINERvA Experiment: getting a closer look at neutrinos Invited Speaker: The discovery that neutrinos oscillate and therefore have mass has led to a broad new program of long baseline neutrino experiments. However, there is still much that we don't know about the way neutrinos themselves interact in nuclei, and this could ultimately limit how well we can measure oscillation probabilities. The MINERvA experiment will use a fine-grained hermetic detector to measure precisely the many ways that few GeV neutrinos interact in different nuclei, using the NuMI beamline at Fermilab. This talk will discuss the physics justification for the MINERvA experiment, give a brief overview of the detector and the status of its construction and commissioning. [Preview Abstract] |
