Goldstini: Smoking-Gun Signatures and Cosmology Nov 17, 2010

Show notes

Jeremy Mardon shows that the BBN bound can be naturally evaded in the presence of multiple sectors which independently break supersymmetry, since there is a new decay channel of the LOSP to a goldstino.

A New Method for Resolving Combinatorial Ambiguities at Hadron Colliders Nov 15, 2010

Show notes

Felix Yu presents a new method for resolving combinatorial ambiguities that arise in multi-particle decay chains at hadron colliders where the assignment of visible particles to the different decay chains has ambiguities.

The Fastest Decay in the Landscape Nov 09, 2010

Show notes

Alex Dahlen shows that the fastest decay is a giant leap to a wildly distant minimum, in which many different fluxes discharge at once.

Singlet-Stabilized Minimal Gauge Mediation Nov 08, 2010

Show notes

David Curtin proposes Singlet Stabilized Minimal Gauge Mediation as a simple ISS-based model of Direct Gauge Mediation which avoids both light gauginos and Landau Poles.

1-loop Renormalization Group Invariants in the MSSM Nov 01, 2010

Show notes

Patrick Draper gives a talk about how if collider experiments demonstrate that the Minimal Supersymmetric Standard Model (MSSM) is a good description of nature at the weak scale, the experimental priority will be the precise determination of superpartner masses.

BSM Searches Using Weak Boson Pair Production Oct 26, 2010

Show notes

Christoph Englert discusses how the upcoming generation of colliders' weak boson production in association with hard jets is going to provide insight into the mechanism of electroweak symmetry breaking.

Asymmetric Dark Matter from a GeV Hidden Sector Oct 25, 2010

Show notes

Tim Cohen discusses how Asymmetric Dark Matter (ADM) models relate the dark matter density to the baryon asymmetry, so that a natural mass scale for ADM is around a few GeV.

Phenomenology of Continuum Superpartners Oct 13, 2010

Show notes

Haiying Cai examines supersymmetric theories with approximately conformal sectors.

Flavor in Minimal Conformal Technicolor Oct 11, 2010

Show notes

Jared Evans constructs a complete, realistic, and natural UV completion of minimal conformal technicolor that explains the origin of quark and lepton masses and mixing angles.

Mass Measurement in Boosted Decay Systems at Hadron Colliders Sep 28, 2010

Show notes

Wonsang Cho reports on a new possibility of using the $\mct2$ (Constransverse mass) variable for mass measurement of single step decay chains involving missing particles with moderate transverse momentum.
