Antisplit Supersymmetry
I explore the phenomenology of Supersymmetry models in which the gauginos are
much heavier then that scalar particles of the MSSM. In these models, the
gauginos are inaccessible to colliders while the scalar spectrum is compressed.
I give several examples of models which exhibit this phenomenology built in the
class of General Gauge Mediated Models. I explore possible LSP and NLSP
candidates in these scenarios including Higgsino, stau, and sneutrino
candidates. Collider signatures for these models include multi-particle decay
chains, many taus in the final state, and possible displaced vertices with
semi-long lived sparticles. I enumerate the most likely collider smoking gun
collider signatures for each general LSP/NLSP scenario.Comment: 26 pages, 7 figures, 6 table
Critique [of Women, Religion, and Peace in an American Indian Ritual by Kristin Herzog]
Herzog\u27s article is organized around three threads which she proposes as useful for strengthening the fabric of contemporary U.S. society. The three threads, teased from an exploration of a portion of the Dekanawida-Hayonwatha stories (narrative and ritual of the Haudenosaunee) are: 1. the high status of women in Haudenosaunee society 2. the understanding of statecraft as a sacred responsibility toward all creation 3. peace as justice and wholeness in the social order. The threads found in stories dating back to about the 15th century provide a view of beliefs denominated by the Haudenosaunee society as being praiseworthy and of good report
Chaotic Hybrid Inflation with a Gauged B - L
In this paper we present a novel formulation of chaotic hybrid inflation in
supergravity. The model includes a waterfall field which spontaneously breaks a
gauged at a GUT scale. This allows for the possibility of future
model building which includes the standard formulation of baryogenesis via
leptogenesis with the waterfall field decaying into right-handed neutrinos. We
have not considered the following issues in this short paper, i.e.
supersymmetry breaking, dark matter or the gravitino or moduli problems. Our
focus is on showing the compatibility of the present model with Planck, WMAP
and Bicep2 data.Comment: 11 pages, 3 figure
New Calculations in Dirac Gaugino Models: Operators, Expansions, and Effects
In this work we calculate important one loop SUSY-breaking parameters in
models with Dirac gauginos, which are implied by the existence of heavy
messenger fields. We find that these SUSY-breaking effects are all related by a
small number of parameters, thus the general theory is tightly predictive. In
order to make the most accurate analyses of one loop effects, we introduce
calculations using an expansion in SUSY breaking messenger mass, rather than
relying on postulating the forms of effective operators. We use this expansion
to calculate one loop contributions to gaugino masses, non-holomorphic SM
adjoint masses, new A-like and B-like terms, and linear terms. We also test the
Higgs potential in such models, and calculate one loop contributions to the
Higgs mass in certain limits of R-symmetric models, finding a very large
contribution in many regions of the -less MSSM, where Higgs fields couple
to standard model adjoint fields.Comment: 16 pages, 10 figure
