Title: Weighing Neutrinos at the LHC through Stop LSP Decays
Host: Ennio Salvioni
Room: 432
Abstract: In the minimal supersymmetric local B-L model, the B-L symmetry must be broken by the vacuum expectation value of the right-handed sneutrino. This spontaneous symmetry breaking triggers R-parity violation but in such a way that the proton remains safe. I will discuss some of the interesting consequences of this theory, especially as they relate to the neutrino sector and the phenomenology of third generation squark LSPs. The surprising connection between the decays of squark LSPs and the neutrino sector will be highlighted.

Title: Black hole entropy in loop quantum gravity
Host: Steve Carlip
Room: 432
Abstract: After briefly introducing the main ingredients of the loop quantum gravity approach, I show how it can applied to the calculation of black hole entropy. I review some well known results and ambiguities in the derivation. Then I introduce a new perspective which might help us to solve the latter and allows us to recover the semiclassical Bekenstein-Hawking entropy formula.

Title: Dark Matter Complementarity
Host: Yuhsin Tsai
Room: 432
Abstract: We perform a detailed study of the so called Z' and Higgs portals using a generic parametrization.
We exploit the complementarity among collider, direct and indirect dark matter detection to outline the excluded versus still viable parameter space regions of those frameworks.

Title: Emerging Jets
Host: Luty
Room: 432
Abstract: I will describe a new collider object we have termed emerging jets.
These can arise when there is a confining dark sector connected to the
Standard Model by a TeV scale mediator, a scenario that is well
motivated by dark matter considerations. The signature of an emerging
jet is O(10) displaced vertices inside the jet each with different
impact parameter, and a small number of prompt tracks. I will describe
strategies that can be used to discover emerging jets even if they
have very small cross sections.

Title: Scale v.s. conformal invariance in four dimensions
Host: M.Luty
Room: 432
Abstract: I argue that every unitary scale invariant theory is conformally invariant in four dimensions.
The argument follows that of Luty, Polchinski and Rattazzi, and is based on additional assumptions that:
(1) A kind of crossing symmetry for vanishing matrix elements holds regardless of the existence of the S-matrix. (2) Correlation functions in momentum space are analytic functions other than singularities and branch cuts coming from on-shell processes. (3) The Wightman axioms are sufficient criteria of the locality of an operator.

Title: Dark Matter as a Fundamental Particle
Host: Kaloper
Room: Roessler 55
Abstract:
In this talk I will review past and present ideas about dark matter as
a new fundamental particle, exploring both the underlying theoretical structures as well as the variety of experimental frontiers. Along the way I will try to give you a flavor of some of the most recent developments as well as future plans and prospects.

Title: NuLat: a near-reactor neutrino detector to study the RAA and for other applications
Host: Svoboda
Room: 432
Abstract:NuLat is a new design for a meter scale electron anti-neutrino
detector, employing the LENS geometry to divide the detector into a
lattice of small cells. Each cell has a totally internally reflecting
boundary, and light from an interaction in one cell goes strongly in the
three cardinal directions, pinning down the interactions with a six fold
coincidence. Effects due to annihilation gammas are minimized by small
cell sizes (6 cm). Not only will this detector have good 5 D resolution
(X,Y,Z,t,E), plus some particle identification, it will reject
backgrounds efficiently, and reject many signatures in real time. The
NuLat team combining the miniTImeCube and LENS groups and others, has
much of the development previously accomplished, and construction is
expected to be underway soon.
