Associate Laboratory Director for Physical Sciences and Engineering Peter B. Littlewood will present "Higgs-like Modes in Condensed Matter and Atomic Physics" Wed., June 12, from 11 to noon, at Bldg. 362, Rm. F108.
We describe simulation studies of a homogeneous total absorption dual readout calorimeter. The simulation assumes that with appropriate dense crystals and optimized readout elements, both scintillation and Cerenkov photons can be produced and detected separately. The correlation between the Cerenkov and Scintillation light then allows to selectively correct particle energies event by event, resulting in improved hadronic energy resolution.
In the ATLAS Detector at the LHC, the Pixel Detector consists of 80 million channels on 1744 modules which are read out using an 80m optical link. The performance of the optical link during the first 4 years of operations will be discussed, as well as the latest diboson electro-weak physics results from ATLAS.
In the first part of the talk, I will review one of the most distinctive signatures of dark matter: its annual modulation direct detection signal, due to the relative motion of the Earth around the Sun.
Two main goals of the spin physics program with STAR at RHIC are to measure the polarization of gluons in the polarized proton and to delineate spin contributions from the light quarks and anti-quarks by flavor. The measurements are being made with collisions of longitudinally polarized protons at 200 and 500 GeV center-of-mass energy. In addition, intriguingly large spin effects have been observed in collisions with transversely polarized beams at forward pseudorapidities. I will discuss the status and outlook.
