Deriving the Inflaton in Compactified M-theory with a De Sitter Vacuum

Gordon Kane, Martin Wolfgang Winkler

Compactifying M-theory on a manifold of holonomy gives a UV complete 4D theory. It is supersymmetric, with soft supersymmetry breaking via gaugino condensation that simultane…

The Baryon-Dark Matter Ratio Via Moduli Decay After Affleck-Dine Baryogenesis

Gordon Kane, Jing Shao, Scott Watson +1

Low-scale supersymmetry breaking in string motivated theories implies the presence of O(100) TeV scale moduli, which generically lead to a significant modification of the history o…

Neutralino Dark Matter from Indirect Detection Revisited

Phill Grajek, Gordon Kane, Daniel J. Phalen +2

We revisit indirect detection possibilities for neutralino dark matter, emphasizing the complementary roles of different approaches. While thermally produced dark matter often requ…

A new (string motivated) approach to the little hierarchy problem

Daniel Feldman, Gordon Kane, Eric Kuflik +1

We point out that in theories where the gravitino mass, , is in the range (10-50)TeV, with soft-breaking scalar masses and trilinear couplings of the same order, there exi…

Is the PAMELA Positron Excess Winos?

Phill Grajek, Gordon Kane, Dan Phalen +2

Recently the PAMELA satellite-based experiment reported an excess of galactic positrons that could be a signal of annihilating dark matter. The PAMELA data may admit an interpretat…

Baryogenesis from a Modulus Dominated Universe

Gordon Kane, Martin Wolfgang Winkler

String/ M-theory compactifications predict the existence of a modulus field with a mass of 100-10000 TeV. Its decay at MeV-temperatures generates large amounts of entropy and washe…

An M theory Solution to the Hierarchy Problem

Bobby Acharya, Konstantin Bobkov, Gordon Kane +2

An old idea for explaining the hierarchy is strong gauge dynamics. We show that such dynamics {\it also} stabilises the moduli in theory compactifications on manifolds of

Exciting Implications of LHC Higgs Boson Data

Gordon Kane

Naively, the LHC Higgs boson looks like a Standard Model Higgs boson, with no guidance to physics beyond the Standard Model, as has often been remarked. The data show that what was…

Bounds on Scalar Masses in Theories of Moduli Stabilization

Bobby Samir Acharya, Gordon Kane, Eric Kuflik

In recent years it has been realised that pre-BBN decays of moduli can be a significant source of dark matter production, giving a `non-thermal WIMP miracle' and substantially redu…

PAMELA Satellite Data as a Signal of Non-Thermal Wino LSP Dark Matter

Gordon Kane, Ran Lu, Scott Watson

Satellite data is accumulating that suggests and constrains dark matter physics. We argue there is a very well motivated theoretical preexisting framework consistent with dark matt…

Flavour issues for string-motivated heavy scalar spectra with a low gluino mass: the G2-MSSM case

Kenji Kadota, Gordon Kane, Joern Kersten +1

In recent years it has been learned that scalar superpartner masses and trilinear couplings should both generically be larger than about 20 TeV at the short distance string scale i…

Extracting the Wavefunction of the LSP at the LHC

Gordon Kane, Eric Kuflik, Brent D. Nelson

We consider associated production of squarks and gluinos with the lightest supersymmetric particle (LSP), or states nearly degenerate in mass with it. Though sub-dominant to pair p…

CP-violating Phases in M-theory and Implications for EDMs

Gordon Kane, Piyush Kumar, Jing Shao

We demonstrate that in effective theories arising from a class of N=1 fluxless compactifications of M-theory on a G2 manifold with low energy supersymmetry, CP-violating phases do…

Dark Matter and LHC: What is the Connection?

Gordon Kane, Scott Watson

We review what can (and cannot) be learned if dark matter is detected in one or more experiments, emphasizing the importance of combining LHC data with direct, astrophysical and co…

Higgs Mass Prediction for Realistic String/M Theory Vacua

Gordon Kane, Piyush Kumar, Ran Lu +1

Recently it has been recognized that in compactified string/M-theories that satisfy cosmological constraints, it is possible to derive some robust and generic predictions for parti…

Should China build the Great Collider?

Stephen Hawking, Gordon Kane

We address the question of the title from the scientific, economic, and cultural points of view, and argue strongly for a positive answer. We respond to various issues that have be…

Cornering (quasi) degenerate neutrinos with cosmology

Massimiliano Lattanzi, Martina Gerbino, Katherine Freese +2

In light of the improved sensitivities of cosmological observations, we examine the status of quasi-degenerate neutrino mass scenarios. Within the simplest extension of the standar…

Neutrino mass matrices from localization in M-theory on orbifold

Eric Gonzalez, Gordon Kane, Khoa Nguyen

M-theory compactified on a manifold with resolved singularity is a promising candidate for a unified theory. The experimentally observed masses of quarks and charged le…

Theory and Phenomenology of mu in M theory

Bobby Samir Acharya, Gordon Kane, Eric Kuflik +1

We consider a solution to the mu-problem within M theory on a G2-manifold. Our study is based upon the discrete symmetry proposed by Witten that forbids the mu-term and solves the…

Studying Gaugino Mass Unification at the LHC

Baris Altunkaynak, Phillip Grajek, Michael Holmes +2

We begin a systematic study of how gaugino mass unification can be probed at the CERN Large Hadron Collider (LHC) in a quasi-model independent manner. As a first step in that direc…

Non-thermal Dark Matter and the Moduli Problem in String Frameworks

Bobby S. Acharya, Piyush Kumar, Konstantin Bobkov +3

We address the cosmological moduli/gravitino problems and the issue of too little thermal but excessive non-thermal dark matter from the decays of moduli. The main examples we stud…

Mixed Wino-Axion Dark Matter in String/M Theory and the 130 GeV Gamma-line "Signal"

Bobby Samir Acharya, Gordon Kane, Piyush Kumar +2

String/M theory compactifications with low energy supersymmetry tend to predict that dark matter has two components: axions and WIMPs \cite{1004.5138,1204.2795}. In accord with thi…

Was the Universe Actually Radiation Dominated Prior to Nucleosynthesis?
