B Decays as a Probe of Spontaneous CP-Violation in SUSY Models
We consider phenomenological implications of susy models with spontaneously
broken CP-symmetry. In particular, we analyze CP-asymmetries in B decays and
find that the predictions of these models are vastly different from those of
the SM. These features are common to NMSSM-like models with an arbitrary number
of sterile superfields and the MSSM with broken R-parity.Comment: Talk given at SUSY'99, 14-19 June, Fermilab, Batavia, I
A second Higgs from the Higgs portal
In the Higgs portal framework, the Higgs field generally mixes with the
Standard Model singlet leading to the existence of two states, one of which is
identified with the 125 GeV scalar observed at the LHC. In this work, we
analyse direct and indirect constraints on the second mass eigenstate and the
corresponding mixing angle. The existence of the additional scalar can be
beneficial as it can stabilise the otherwise-metastable electroweak vacuum. We
find parameter regions where all of the bounds, including the stability
constraints, are satisfied. We also study prospects for observing the decay of
the heavier state into a pair of the 125 GeV Higgs-like scalars.Comment: 16 pages, updated figures 3 and 4 with new limits from Higgs-searches

SUSY Phenomenology of KKLT Flux Compactifications
We study SUSY phenomenology of the KKLT (Kachru-Kallosh-Linde-Trivedi)
scenario of string theory compactifications with fluxes. This setup leads to a
specific pattern of soft masses and distinct phenomenological properties. In
particular, it avoids the cosmological gravitino/moduli problems. Remarkably,
the model allows for the correct abundance of SUSY dark matter consistently
with all experimental constraints including the bound on the Higgs mass, b-->s
gamma, etc. This occurs for both small and large tan beta, and requires the
SUSY spectrum above 1 TeV.Comment: 23 pages, 8 figures; v2: erratum attache
