The Tau Portal workshop will bring together experimentalists and theorists to discuss present and future signals with one or more taus. We will examine the state of the art with regard to how to isolate taus at the Tevatron and LHC and what kind of sensitivity can be achieved for new physics, comparing to sensitivity using electrons and muons and detailing new physics situations where taus provide the greater sensitivity.
SUSY Recast will focus on using the analyses that are currently available for limits (assuming no discovery by the time of the workshop) on supersymmetric models and on recasting/reusing these limits to place limits on models that have not been analyzed by the experimental community. The idea is to develop a procedure for a theorist to propose a model, send new physics events generated in this model to the experimental collaborations at the LHC, and have the experimental collaborations come back quickly with the limits on the new model.

Title: Identifying physics Beyond the Standard Model at the LHC
Host: Luty
Room: 432
Many BSM theories predict new heavy particle states that are
identical to their SM counterparts but are heavier. In SUSY, the
superpartners differ in spin by a half-integer from their SM counterparts,
whereas Kaluza-Klein resonances have the same spin as the SM zero modes.
Measuring spin thus provides a crucial handle on distinguishing new physics
models at the LHC. The first part of this talk is about spin measurement of
new particles at the LHC using the azimuthal angular distribution of decay
products from a parent particle whose spin we wish to measure. This
technique is model independent and relies only on simple angular momentum
rules and quantum mechanics. In the second part of the talk we discuss WZ
scattering at the LHC. We find that the same azimuthal angle can be used as
a probe of a strongly coupled Higgs sector.

Title: Lower Limits on the Strengths of Gamma Ray Lines from Dark Matter Annihilation
Host: Markus Luty
Room: 432
I will discuss the spectrum of gamma ray signals that arises from dark matter annihilation in the universe. I will focus on the large class of theories where the photon spectrum includes both diffuse gamma rays that arise from annihilation into Standard Model states at tree level, as well as monochromatic gamma rays arising from annihilation directly into two photons at the one loop level. In this class of theories I will obtain lower bounds on the ratio of the strength of the gamma ray line relative to the gamma ray continuum as a function of the dark matter mass and spin. These limits arise from the unitarity relation between the imaginary parts of the matrix elements of the loop diagrams that generate the line signal and the tree level amplitudes for dark matter annihilation into the intermediate states running in the loop and for their subsequent annihilation into two photons. These results are exact in the limit that dark matter annihilation is exclusively to a single Standard Model species, occurs through the lowest partial wave and respects CP. Away from this limit the bounds are approximate. These results agree with the known results in the literature in the case of the Minimal Supersymmetric Standard Model (MSSM).

Title:Charmless semileptonic B decays and |Vub| at BaBar
Host: Robin Erbacher
Room: 416
The magnitude of Vub can be used to test for physics beyond the Standard Model by placing a redundant constraint on the unitarity of the CKM matrix. I will present the results of two exclusive measurements of |Vub|, using B-->(pi/rho) l nu and B-->omega l nu decays. The combined study of B-->pi l nu and B-->rho l nu has made one of the most precise single determinations of |Vub|. The B-->omega l nu analysis uses data from the omega mass sidebands to describe the dominant background, and has made the first measurement of the B-->omega l nu q2 spectrum.
