High-energy physics

2015 IEEE Nuclear Science Symposium and Medical Imaging Conference

22nd Symposium on Room-Temperature Semiconductor X-ray and Gamma-ray Detectors

This conference will be held Saturday, October 31 - Saturday, November 7, 2015 at the Town and Country Hotel in San Diego, California.

Precision Physics at the LHC: Yesterday, Today and Tomorrow
There has been a great deal of progress towards precision calculations for physics processes at the LHC. I will discuss the new Les Houches Precision Physics Wishlist, introduced in 2013, and discuss the physics motivations for the QCD(+EW) calculations on the list, in terms of the current precision, and the expected improvements to that precision, for experimental measurements at the LHC.

JET and Other Objects
Recently Howard Georgi introduced a new way to cluster particles into jets for e+e- machine. The particles belong to the jets are selected to maximize certain jet function. We extended the jet functions to hadron collider and created a algorithm fast enough for semi-realistic simulations. It is also possible to generalize the idea to more complicated objects like W/Z.

Searches for Supersymmetry at the LHC and Discovery Potential of the High-Luminosity LHC
Supersymmetry is arguably the most promising theory for physics beyond the Standard Model. In this talk I review searches for Supersymmetry in the 8 TeV proton-proton collision data delivered by the LHC and collected by the ATLAS detector with a focus on electro-weakinos. The discovery potential is expected to significantly increase at the High-Luminosity LHC providing 3000/fb at 14 TeV. I will present plans for the upgrade of the ATLAS detector, its expected performance as well as the physics prospects.

Jet Physics at the LHC Run II
This year marks the beginning of the second run of the LHC. The increased center-of-mass energy will make more stringent studies of properties properties of the Higgs boson possible and it will extend the reach of searches of physics Beyond the Standard Model. The exploration of this new energy regime cannot be successful without a careful (re)consideration of Standard Model processes and backgrounds, often dominated by strong interactions.
Search for W to tb in the Hadronic Final State at ATLAS
Before 2014, the search for a massive W' gauge boson in the decay channel of tb was only carried out with top decaying leptonically into lνb. This talk presents the first result on W tb with top decaying hadronically into qqb, performed with data corresponding to 20.3/fb of integrated luminosity collected by the ATLAS detector at the LHC in pp collisions at a center-of- mass energy of sqrt(s) = 8 TeV. This analysis searches for W with masses above 1.5 TeV, where the W' decay products have large momentum.
Tiny Bubbles in the Mine: Latest Results from the PICO Collaboration
The PICO Collaboration (formerly COUPP) builds bubble chambers for the direct detection of dark matter. Observations on scales ranging from single galaxies to the entire visible universe all require a dark matter density five times that of normal matter. Nobody knows what the dark matter is, but all known particles have been excluded, making the existence of dark matter one of the strongest indications we have for particle physics beyond the standard model.
