Gauge Mediated Mini-Split
We propose a simple model of split supersymmetry from gauge mediation. This
model features gauginos that are parametrically a loop factor lighter than
scalars, accommodates a Higgs boson mass of 125 GeV, and incorporates a simple
solution to the problem. The gaugino mass suppression can be
understood as resulting from collective symmetry breaking. Imposing collider
bounds on and requiring viable electroweak symmetry breaking implies
small -terms and small -- the stop mass ranges from to
10^8 \mbox{ GeV}. In contrast with models with anomaly + gravity mediation
(which also predict a one-loop loop suppression for gaugino masses), our gauge
mediated scenario predicts aligned squark masses and a gravitino LSP. Gluinos,
electroweakinos and Higgsinos can be accessible at the LHC and/or future
colliders for a wide region of the allowed parameter space.Comment: 16 pages, 1 figure. Journal version, references adde
Towards a classifier for digital sensitivity review
The sensitivity review of government records is essential before they can be released to the official government archives, to prevent sensitive information (such as personal information, or that which is prejudicial to international relations) from being released. As records are typically reviewed and released after a period of decades, sensitivity review practices are still based on paper records. The transition to digital records brings new challenges, e.g. increased volume of digital records, making current practices impractical to use. In this paper, we describe our current work towards developing a sensitivity review classifier that can identify and prioritise potentially sensitive digital records for review. Using a test collection built from government records with real sensitivities identified by government assessors, we show that considering the entities present in each record can markedly improve upon a text classification baseline
