Title: Composite Weak Bosons at the LHC
Host: Jack Gunion
Room: 416
Abstract: The weak bosons are composite systems.
The constituents are confined like the quarks in a
rho meson. The substructure scale is estimated to be
of the order of 0.5 TeV. A new isoscalar neutral weak
boson must exist. Its mass should not exceed 1 TeV.
Excitations of the weak bosons can be produced at the
LHC. The lowest p-wave state is identified with the
particle, which might have been observed at the LHC
with a mass of 126 GeV. A substructure for the weak bosons implies also a substructure for the leptons and quarks, which should soon be observed at the LHC.

Title: Search for New Physics in Same-sign dilepton production in ATLAS
Host: Maxwell Chertok
Room: 416
The experimental signature of two leptons with the same electric charge is a great way to search for new physics as the backgrounds from Standard Model processes are quite low and a large variety of new physics models can produce this signature, e.g models with extended Higgs sectors, Supersymmetry, additional quark generations, and many more. I will review the ATLAS analyses in this signature based on the 2011 LHC data.

Title: A natural 125 GeV Higgs in the NMSSM
Host: John Terning
Room: 432
Abstract: We look for a golden region in the parameter space of the NMSSM with a low cut-off where a SM-like Higgs with a mass m_h ~ 125 GeV can be obtained in a minimal bottom-up approach of field content.

Title: The World's Smallest Neutrino Detector, and Long Range Monitoring with Neutrinos
Host: Bob Svoboda
Room: 416
Abstract:We are building a two liter neutrino detector, called the miniTImeCube, which will measure neutrinos near reactors via the Reines process, inverse beta decay. The detector employs 24x64 very fast pixels with waveform digitization to achieve unprecedented event millimeter
resolution. The signals are streamed via the digital signal processors, and hence backgrounds can be suppressed on the fly. A consequence of the
tiny detector size and online filtering of the data is the lack of need for shielding. The whole package including power supplies, data acquisition and computers fits in a pair of cases which stack to form a module about the size of a single electronics rack, or about one square meter of floor space. We hope to test this device at a reactor in the next few months.
Secondly, I will report on our studies of long range nuclear reactor monitoring via neutrinos. We have done extensive calculations,
including all backgrounds as known from exiting experiments, and including modeling of the geoneutrino background (in 3D). We have
christened our proposed method as NuDAR, since we find that with even a few neutrino events, the energy distribution as modulated by
oscillations, exerts a powerful constraint, even from one detector, while two detectors yields locational solutions. Moreover neutrino
directional resolution in a given detector exerts very powerful constraints. With even modest directionality, and if not too many
distracting reactors in the area, a single detector can get useful range and azimuth. If one knows the reactor location, this can be used to
constrain observation of operation and power. While very large neutrino detectors are required for these purposes, we can foresee a time when a
world network of such detectors can become practical. The spinoffs for particle physics and astrophysics are bountiful.

Title: The ATLAS experiment at the LHC
Host: Richard Lander
Room: 416
Abstract:
Both the ATLAS and CMS detectors have operated with high efficiency in the first two years of LHC operation and produced an impressive number of physics results. In this talk I will discuss some of the differences between the detectors and describe some unique features of the ATLAS detector and how these features have been exploited in our physics analyses. I will describe some selected recent results and conclude with an overview of the planned, near term ATLAS detector upgrades.
