Low-energy Observables and General Gauge Mediation in the MSSM and NMSSM

We study constraints on the general gauge mediation (GGM) parameter space
arising from low-energy observables in the MSSM and NMSSM. Specifically, we
look at the dependence of the spectra and observables on the correlation
function ratios in the hidden sector where supersymmetry is presumably broken.
Since these ratios are not a priori constrained by theory, current results from
the muon anomalous magnetic moment and flavor physics can potentially provide
valuable intuition about allowed possibilities. It is found that the muon
anomalous magnetic moment and flavor-physics observables place significant
constraints on the GGM parameter space with distinct dependences on the hidden
sector correlation function ratios. The particle spectra arising in GGM, with
the possibility of different correlation function ratios, is contrasted with
common intuition from regular gauge mediation (RGM) schemes (where the ratios
are always fixed). Comments are made on precision gauge coupling unification,
topography of the NLSP space, correlations of the muon anomalous magnetic
moment with other observables, and approximate scaling relations in sparticle
masses with respect to the high-scale correlation function ratios.Comment: 43 pages, 16 figures. Typos corrected, updated references,

Massless D-strings and moduli stabilization in type I cosmology

We consider the cosmological evolution induced by the free energy F of a gas
of maximally supersymmetric heterotic strings at finite temperature and weak
coupling in dimension D>=4. We show that F, which plays the role of an
effective potential, has minima associated to enhanced gauge symmetries, where
all internal moduli can be attracted and dynamically stabilized. Using the fact
that the heterotic/type I S-duality remains valid at finite temperature and can
be applied at each instant of a quasi-static evolution, we find in the dual
type I cosmology that all internal NS-NS and RR moduli in the closed string
sector and the Wilson lines in the open string sector can be stabilized. For
the special case of D=6, the internal volume modulus remains a flat direction,
while the dilaton is stabilized. An essential role is played by light D-string
modes wrapping the internal manifold and whose contribution to the free energy
cannot be omitted, even when the type I string is at weak coupling. As a
result, the order of magnitude of the internal radii expectation values on the
type I side is (lambda_I alpha')^{1/2}, where lambda_I is the ten-dimensional
string coupling. The non-perturbative corrections to the type I free energy can
alternatively be described as effects of "thermal E1-instantons", whose
worldsheets wrap the compact Euclidean time cycle.Comment: 39 pages, 1 figur
Intersecting black branes in strong gravitational waves

We consider intersecting black branes with strong gravitational waves
propagating along their worldvolume in the context of supergravity theories.
Both near-horizon and space-filling gravitational wave modes are included in
our ansatz. The equations of motion (originally, partial differential
equations) are shown to reduce to ordinary differential equations, which
include a Toda-like system. For special arrangements of intersecting black
branes, the Toda-like system becomes integrable, permitting a more thorough
analysis of the gravitational equations of motion.Comment: 17 pages; v2: cosmetic improvements, published versio
Supergroup - extended super Liouville correspondence

We derive a relation between correlation functions of supergroup WZNW models
and conformal field theories with extended superconformal symmetry. The
supergroups considered have a bosonic subgroup of the form SL(2) x A for some
Lie group A. The corresponding conformal field theory is a super Liouville
field theory coupled with the WZNW model on A. An example is a correspondence
between the PSU(1,1|2) WZNW model and small N=4 super Liouville field theory.
The OSP(n|2) WZNW model is related to a superconformal field theory with SO(n)
extended superconformal symmetry of the Knizhnik-Bershadsky type. In the case
n=4 this is simply the large N=(4,4) superconformal symmetry. Besides these two
examples we make a general derivation encompassing the WZNW models on
supergroups SL(2|n), D(2,1;\alpha), OSP(4|2n), F(4) and G(3) and their relation
to models with extended superconformal algebras as symmetry.Comment: 30 page
Easy dirac gauginos.

A simple and natural model is presented that gives Dirac gauginos. The configuration is related to “deconstructed gaugino mediation”. A high energy completion is provided based on existing ISS-like models of deconstructed gaugino mediation. This provides a complete picture of Dirac gauginos that includes the necessary extra adjoint fermions (generated as magnetic quarks of the ISS theory) and supersymmetry breaking (via the ISS mechanism). Moreover the screening of the scalar masses means that they can be similar to or less than the gaugino masses, even though the supersymmetry breaking is driven by F-terms
Multiple D4-D2-D0 on the Conifold and Wall-crossing with the Flop

We study the wall-crossing phenomena of D4-D2-D0 bound states with two units
of D4-brane charge on the resolved conifold. We identify the walls of marginal
stability and evaluate the discrete changes of the BPS indices by using the
Kontsevich-Soibelman wall-crossing formula. In particular, we find that the
field theories on D4-branes in two large radius limits are properly connected
by the wall-crossings involving the flop transition of the conifold. We also
find that in one of the large radius limits there are stable bound states of
two D4-D2-D0 fragments.Comment: 24 pages, 4 figures; v2: typos corrected, minor changes, a reference

Correlations in double parton distributions at small x

We present a dynamical study of the double parton distribution in impact
parameter space, which enters into the double scattering cross section in
hadronic collisions. This distribution is analogous to the generalized parton
densities in momentum space. We use the Lund Dipole Cascade model, presented in
earlier articles, which is based on BFKL evolution including essential higher
order corrections and saturation effects. As result we find large correlation
effects, which break the factorization of the double scattering process. At
small transverse separation we see the development of "hot spots", which become
stronger with increasing Q^2. At smaller x-values the distribution widens,
consistent with the shrinking of the diffractive peak in elastic scattering.
The dependence on Q^2 is, however, significantly stronger than the dependence
on x, which has implications for extrapolations to LHC, e.g. for results for
underlying events associated with the production of new heavy particles.Comment: 19 pages v2: minor clarifications added. v3: citation added; JHEP

Electroweak corrections to dilepton + jet production at hadron colliders

The first calculation of the next-to-leading-order electroweak corrections to
Z-boson + jet hadroproduction including leptonic Z-boson decays is presented,
i.e. to the production of a charged lepton--anti-lepton final state in
association with one hard jet at the LHC and the Tevatron. The Z-boson
resonance is treated consistently using the complex-mass scheme, and all
off-shell effects as well as the contributions of the intermediate photon are
taken into account. The corresponding next-to-leading-order QCD corrections
have also been recalculated. The full calculation is implemented in a flexible
Monte Carlo code. Numerical results for cross sections and distributions of
this Standard Model benchmark process are presented for the Tevatron and the
LHC.Comment: 32 pages, 13 figures. v2, further phenomenological results included,

First-order flows and stabilisation equations for non-BPS extremal black holes

28 páginas.-- This article is distributed under the terms of the Creative Commons\ud

Based on this, we propose a generic ansatz for the stabilisation equations, which surprisingly includes ratios of harmonic functions.The work of P.G. has been supported in part by grants FIS2008-06078-\ud

N=8 Counterterms and E7(7) Current Conservation

We examine conservation of the E7(7) Noether-Gaillard-Zumino current in the
presence of N=8 supergravity counterterms using the momentum space helicity
formalism, which significantly simplifies the calculations. The main result is
that the 4-point counterterms at any loop order L are forbidden by the E7(7)
current conservation identity. We also clarify the relation between linearized
and full non-linear superinvariants as candidate counterterms. This enables us
to show that all n-point counterterms at L=7, 8 are forbidden since they
provide a non-linear completions of the 4-point ones. This supports and
exemplifies our general proof in arXiv:1103.4115 of perturbative UV finiteness
of N=8 supergravity.Comment: 18 page
Generalized Geometry and M theory

We reformulate the Hamiltonian form of bosonic eleven dimensional
supergravity in terms of an object that unifies the three-form and the metric.
For the case of four spatial dimensions, the duality group is manifest and the
metric and C-field are on an equal footing even though no dimensional reduction
is required for our results to hold. One may also describe our results using
the generalized geometry that emerges from membrane duality. The relationship
between the twisted Courant algebra and the gauge symmetries of eleven
dimensional supergravity are described in detail.Comment: 29 pages of Latex, v2 References added, typos fixed, v3 corrected

Search for new physics with same-sign isolated dilepton events with jets and missing transverse energy at the LHC

The results of searches for new physics in events with two same-sign isolated leptons, hadronic jets, and missing transverse energy in the final state are presented. The searches use an integrated luminosity of 35 pb−1 of pp collision data at a centre-of-mass energy of 7TeV collected by the CMS experiment at the LHC. The observed numbers of events agree with the standard model predictions, and no evidence for new physics is found. To facilitate the interpretation of our data in a broader range of new physics scenarios, information on our event selection, detector response, and efficiencies is provided.Peer Reviewe
Small Black Hole Constituents and Horizontal Symmetry

By exploiting the role of the horizontal symmetry SL(2,R), we extend the
analysis and classification of two-centered extremal black hole charge
configurations to the case of "small" single-centered constituents. These
latter are seen to decrease the number of independent horizontal-invariant
polynomials from four to one, depending on the rank of the charge orbit
supporting each of the two centers. Within U-duality groups of type E7, both
reducible and irreducible symmetric supergravity models in four space-time
dimensions are considered, thus encompassing N = 2 and N = 8 theories.Comment: 1+24 pages, 3 Table
An effective theory for jet propagation in dense QCD matter: jet
  broadening and medium-induced bremsstrahlung

Two effects, jet broadening and gluon bremsstrahlung induced by the
propagation of a highly energetic quark in dense QCD matter, are reconsidered
from effective theory point of view. We modify the standard Soft Collinear
Effective Theory (SCET) Lagrangian to include Glauber modes, which are needed
to implement the interactions between the medium and the collinear fields. We
derive the Feynman rules for this Lagrangian and show that it is invariant
under soft and collinear gauge transformations. We find that the newly
constructed theory SCET$_{\rm G}$ recovers exactly the general result for the
transverse momentum broadening of jets. In the limit where the radiated gluons
are significantly less energetic than the parent quark, we obtain a jet
energy-loss kernel identical to the one discussed in the reaction operator
approach to parton propagation in matter. In the framework of SCET$_{\rm G}$ we
present results for the fully-differential bremsstrahlung spectrum for both the
incoherent and the Landau-Pomeranchunk-Migdal suppressed regimes beyond the
soft-gluon approximation. Gauge invariance of the physics results is
demonstrated explicitly by performing the calculations in both the light-cone
and covariant $R_{\xi}$ gauges. We also show how the process-dependent
medium-induced radiative corrections factorize from the jet production cross
section on the example of the quark jets considered here.Comment: 52 pages, 15 pdf figures, as published in JHE
Five-dimensional SYM from undeformed ABJM

We expand undeformed ABJM theory around the vacuum solution that was found in
arxiv:0909.3101. This solution can be interpreted as a circle-bundle over a
two-dimensional plane with a singularity at the origin. By imposing periodic
boundary conditions locally far away from the singularity, we obtain a local
fuzzy two-torus over which we have a circle fibration. By performing
fluctuation analysis we obtain five-dimensional SYM with the precise value on
the coupling constant that we would obtain by compactifying multiple M5 branes
on the vacuum three-manifold. In the resulting SYM theory we also find a
coupling to a background two-form.Comment: 23 page
Uniqueness and nonuniqueness of the stationary black holes in 5D
  Einstein-Maxwell and Einstein-Maxwell-dilaton gravity

In the present paper we investigate the general problem of uniqueness of the
stationary black solutions in 5D Einstein-Maxwell-dilaton gravity with
arbitrary dilaton coupling parameter containing the Einstein-Maxwell gravity as
a particular case. We formulate and prove uniqueness theorems classifying the
stationary black hole solutions in terms of their interval structure, electric
and magnetic charges and the magnetic fluxes. The proofs are based on the
nonpositivity of the Riemann curvature operator on the space of the potentials
which imposes restrictions on the dilaton coupling parameter.Comment: 21 pages, LaTe
Supersymmetric Higgs Yukawa Couplings to Bottom Quarks at
  next-to-next-to-leading Order

The effective bottom Yukawa couplings are analyzed for the minimal
supersymmetric extension of the Standard Model at two-loop accuracy within
SUSY-QCD. They include the resummation of the dominant corrections for large
values of tg(beta). In particular the two-loop SUSY-QCD corrections to the
leading SUSY-QCD and top-induced SUSY-electroweak contributions are addressed.
The residual theoretical uncertainties range at the per-cent level.Comment: 25 pages, 9 figures, added comments and references, typos corrected,

Holographic three-point functions of giant gravitons

Working within the AdS/CFT correspondence we calculate the three-point
function of two giant gravitons and one pointlike graviton using methods of
semiclassical string theory and considering both the case where the giant
gravitons wrap an S^3 in S^5 and the case where the giant gravitons wrap an S^3
in AdS_5. We likewise calculate the correlation function in N=4 SYM using two
Schur polynomials and a single trace chiral primary. We find that the gauge and
string theory results have structural similarities but do not match perfectly,
and interpret this in terms of the Schur polynomials' inability to interpolate
between dual giant and pointlike gravitons.Comment: 21 page
The Boundary Multiplet of N=4 SU(2)xU(1) Gauged Supergravity on
  Asymptotically-AdS_5

We consider N=4 SU(2)xU(1) gauged supergravity on asymptotically-AdS_5
backgrounds. By a near-boundary analysis we determine the boundary-dominant
components of the bulk fields from their partially gauge-fixed field equations.
Subdominant components are projected out in the boundary limit and we find a
reduced set of boundary fields, constituting the N=2 Weyl multiplet. The
residual bulk symmetries are found to act on the boundary fields as
four-dimensional diffeomorphisms, N=2 supersymmetry and (super-)Weyl
transformations. This shows that the on-shell N=4 supergravity multiplet yields
the N=2 Weyl multiplet on the boundary with the appropriate local N=2
superconformal transformations. Building on these results we use the AdS/CFT
conjecture to calculate the Weyl anomaly of the dual four-dimensional
superconformal field theories in a generic bosonic N=2 conformal supergravity
background.Comment: 23 pages; to appear in JHE
On the Effective Description of Large Volume Compactifications

We study the reliability of the Two-Step moduli stabilization in the type-IIB
Large Volume Scenarios with matter and gauge interactions. The general analysis
is based on a family of N=1 Supergravity models with a factorizable Kaehler
invariant function, where the decoupling between two sets of fields without a
mass hierarchy is easily understood. For the Large Volume Scenario particular
analyses are performed for explicit models, one of such developed for the first
time here, finding that the simplified version, where the Dilaton and Complex
structure moduli are regarded as frozen by a previous stabilization, is a
reliable supersymmetric description whenever the neglected fields stand at
their leading F-flatness conditions and be neutral. The terms missed by the
simplified approach are either suppressed by powers of the Calabi-Yau volume,
or are higher order operators in the matter fields, and then irrelevant for the
moduli stabilization rocedure. Although the power of the volume suppressing
such corrections depends on the particular model, up to the mass level it is
independent of the modular weight for the matter fields. This at least for the
models studied here but we give arguments to expect the same in general. These
claims are checked through numerical examples. We discuss how the factorizable
models present a context where despite the lack of a hierarchy with the
supersymmetry breaking scale, the effective theory still has a supersymmetric
description. This can be understood from the fact that it is possible to find
vanishing solution for the auxiliary components of the fields being integrated
out, independently of the remaining dynamics. Our results settle down the
question on the reliability of the way the Dilaton and Complex structure are
treated in type-IIB compactifications with large compact manifold volumina.Comment: 23 pages + 2 appendices (38 pages total). v2: minor improvements,

Conclusions from CDF Results on CP Violation in D^0 \to \pi^+\pi^-,
  K^+K^- and Future Tasks

Within the Standard Model (SM) one predicts both direct and indirect CP
violation in D^0 \to \pi^+\pi^-, K^+K^- transitions, although the effects are
tiny: Indirect CP asymmetry cannot exceed O(10^{-4}), probably even O(10^{-5});
direct effects are estimated at not larger than 10^{-4}. At B factories direct
and indirect asymmetries have been studied with <t>/\tau_{D^0} ~ 1; no CP
asymmetry was found with an upper bound of about 1%. CDF has shown intriguing
data on CP violation in D^0 \to \pi^+\pi^- [K^+K^-] with <t>/\tau_{D^0} ~ 2.4
[2.65]. Also, CDF has not seen any CP violation. For direct CP asymmetry, CDF
has a sensitivity similar to the combination of the B factories, yet for
indirect CP violation it yields a significantly smaller sensitivity of
a_{cp}^{ind}=(-0.01 +- 0.06_{stat} +- 0.05_{syst})% due to it being based on
longer decay times. New Physics models (NP) like Little Higgs Models with
T-Parity (LHT) can produce an indirect CP asymmetry up to 1%; CDF's findings
thus cover the upper range of realistic NP predictions ~ 0.1 - 1%. One hopes
that LHCb and a Super-Flavour Factory will probe the lower range down to
~0.01%. Such non-ad-hoc NP like LHT cannot enhance direct CP violation
significantly over the SM level in D^0 \to \pi^+\pi^-, K^+K^- and D^{\pm} \to
\pi^{\pm}K^+K^- transitions, but others might well do so.Comment: 11 pages, 1 figure. V2 has minor corrections and corresponds to the

Can the correlated stability conjecture be saved?

Correlated stability conjecture (CSC) proposed by Gubser and Mitra [1,2]
linked the thermodynamic and classical (in)stabilities of black branes. In [3]
it was shown that the thermodynamic instabilities, specifically the negative
specific heat, indeed result in the instabilities in the hydrodynamic spectrum
of holographically dual plasma excitations. Counter-examples of CSC were
presented in the context of black branes with scalar hair undergoing a
second-order phase transition [4,5]. The latter translationary invariant
horizons have scalar hair, raising the question whether the asymptotic
parameters of the scalar hair can be appropriately interpreted as additional
charges leading to a generalization of the thermodynamic stability criterion.
In this paper we show that the generalization of the thermodynamic stability
criterion of this type can not save CSC. We further present a simple
statistical model which makes it clear that thermodynamic and dynamical
(in)stabilities generically are not correlated.Comment: 9 pages, 2 figures; v2: JHEP versio
On the Quantitative Impact of the Schechter-Valle Theorem

We evaluate the Schechter-Valle (Black Box) theorem quantitatively by
considering the most general Lorentz invariant Lagrangian consisting of
point-like operators for neutrinoless double beta decay. It is well known that
the Black Box operators induce Majorana neutrino masses at four-loop level.
This warrants the statement that an observation of neutrinoless double beta
decay guarantees the Majorana nature of neutrinos. We calculate these
radiatively generated masses and find that they are many orders of magnitude
smaller than the observed neutrino masses and splittings. Thus, some lepton
number violating New Physics (which may at tree-level not be related to
neutrino masses) may induce Black Box operators which can explain an observed
rate of neutrinoless double beta decay. Although these operators guarantee
finite Majorana neutrino masses, the smallness of the Black Box contributions
implies that other neutrino mass terms (Dirac or Majorana) must exist. If
neutrino masses have a significant Majorana contribution then this will become
the dominant part of the Black Box operator. However, neutrinos might also be
predominantly Dirac particles, while other lepton number violating New Physics
dominates neutrinoless double beta decay. Translating an observed rate of
neutrinoless double beta decay into neutrino masses would then be completely
misleading. Although the principal statement of the Schechter-Valle theorem
remains valid, we conclude that the Black Box diagram itself generates
radiatively only mass terms which are many orders of magnitude too small to
explain neutrino masses. Therefore, other operators must give the leading
contributions to neutrino masses, which could be of Dirac or Majorana nature.Comment: 18 pages, 4 figures; v2: minor corrections, reference added, matches
