Abstract Recently, there are two hints arising from physics beyond the standard model. One is a possible energy loss mechanism due to emission of very weakly interacting light particles from white dwarf stars, with a coupling strength ∼ 0.7 × 10 − 13 , and another is the high energy positrons observed by the PAMELA satellite experiment. We construct a supersymmetric flipped-SU(5) model, SU ( 5 ) × U ( 1 ) X with appropriate additional symmetries, [ U ( 1 ) H ] gauge × [ U ( 1 ) R × U ( 1…

PAMELA/ATIC anomaly from the meta-stable extra dark matter component and the leptophilic Yukawa interaction
We present a supersymmetric model with two dark matter (DM) components explaining the galactic positron excess observed by PAMELA/HEAT and ATIC/PPB-BETS: One is the conventional (bino-like) lightest
PAMELA/ATIC Anomaly from Exotic Mediated Dark Matter Decay
We discuss dark matter decay mediated by exotically charged particles (``exotics'') in a supersymmetric model with two dark matter (DM) components: one is the (bino-like) lightest supersymmetric
Decaying LSP in SO(10) GUT and PAMELA's Cosmic Positron
Abstract We suppose that the lightest supersymmetric particle (LSP) in the minimal supersymmetric standard model (MSSM) is the dark matter. The bino-like LSP can decay through the SO ( 10 ) gauge
Dark matter and collider phenomenology of split-UED
We explicitly show that split-universal extra dimension (split-UED), a recently suggested extension of universal extra dimension (UED) model, can nicely explain recent anomalies in cosmic-ray
Parameters in a class of leptophilic dark matter models from PAMELA, ATIC and FERMI
In this work we study a class of leptophilic dark matter models, where the dark matter interacts with the standard model particles via the U(1)L(i)-L(j) gauge boson, to explain the e(+/-) excess in
PAMELA's cosmic positron from decaying LSP in SO(10) SUSY GUT
We propose two viable scenarios explaining the recent observations on cosmic positron excess. In both scenarios, the present relic density in the Universe is assumed to be still supported by
Axinos as dark matter particles
The identification of dark matter in our particle physics model is still an open question. Here, we argue that axinos can be successful dark matter candidates in models with supersymmetry and the
ATIC and PAMELA Results on Cosmic e+- Excesses and Neutrino Masses
Recently the ATIC and PAMELA collaborations released their results which show the abundant e(+/-) excess in cosmic rays well above the background, but not for the (p) over bar. Their data if
DARK MATTER ANNIHILATION EXPLANATION FOR e± EXCESSES IN COSMIC RAY
Recently data from PAMELA, ATIC, FERMI-LAT and HESS show that there are e± excesses in the cosmic ray energy spectrum. PAMELA shown excesses only in e+, but not in anti-proton spectrum. ATIC,
Indirect Dark Matter Signals from EGRET and PAMELA compared
Dark Matter annihilation (DMA) may yield an excess of gamma rays and antimatter particles, like antiprotons and positrons, above the background from cosmic ray interactions. The excess of diffuse

An improved flipped SU(5)×U(1) model from the four-dimensional string
We discuss a four-dimensional string model whose effective field theory is a supersymmetric flipped SU(5)×U(1) GUT with the following properties. • - The quark and lepton mass matrices have a

The galactic 511 keV line from electroweak scale WIMPs
Abstract We consider possible mechanisms via which electroweak scale WIMPs χ 0 could provide the source of the INTEGRAL/SPI 511 keV photon flux from the galactic centre. We consider scenarios where
Superstring standard model from ℤ12−I orbifold compactification with and without exotics, and effective R-parity
We construct a supersymmetric standard model in the context of the 12−I orbifold compactification of the heterotic string theory. The gauge group is SU(3)c × SU(2)L × U(1)Y × U(1)4 × [SO(10) ×
Axino light dark matter and neutrino masses with R-parity violation
Motivated by the recent observation of the 511 keV γ-ray line emissions from the galactic bulge and an explanation for it by the decays of light dark matter particles, we consider the light axino

Abstract We investigate the possibility that dark matter could be made of scalar candidates and focus, in particular, on the unusual mass range between a few MeVs and a few GeVs. After showing why
Constraints on variant axion models
A particular class of variant axion models with two Higgs doublets and a singlet is studied. In these models the axion couples either to the u quark or t quark or both, but not to b, c, s, or d. When
A VIABLE AXION MODEL
Abstract It is discussed whether an axion-like excitation can be the source for the monoenergetic positrons observed at GSI. Although a direct extension of the original Peccei-Quinn model is
Secluded WIMP Dark Matter
We consider a generic mechanism via which thermal relic WIMP dark matter may be decoupled from the Standard Model, namely through a combination of WIMP annihilation to metastable mediators with
Exciting dark matter and the INTEGRAL/SPI 511 keV signal
We propose a dark matter candidate with an 'excited state' 1-2 MeV above the ground state, which may be collisionally excited and deexcites by e{sup +}e{sup -} pair emission. By converting its
