Probing dark matter decay and annihilation with Fermi LAT observations of nearby galaxy clusters
TL;DR: In this article, the authors analyzed the gamma-ray flux coming from eight nearby clusters individually as well as in a combined likelihood analysis, and derived limits on the dark matter lifetime and annihilation cross-section.

The PAMELA Positron Excess from Annihilations into a Light Boson
TL;DR: In this paper, the authors revisited an earlier proposal, wherein the dark matter annihilates into a new light (GeV) boson, which is kinematically constrained to go to hard leptonic states, without anti-protons or π0's.

TL;DR: In this paper, the authors performed global fits to the parameters of the constrained minimal supersymmetric standard model (CMSSM) and a variant with non-universal Higgs masses (NUHM1) and found that the description of low-energy observables, (g-2)(mu) in particular, and the non-observation of SUSY at the LHC become more and more incompatible within the CMSSM.

Implications for the Constrained MSSM from a new prediction for b to s gamma
TL;DR: In this article, the authors re-examine the properties of the Constrained MSSM in light of updated constraints, paying particular attention to the impact of the recent substantial shift in the Standard Model prediction for → Xsγ.
Journal ArticleDOI
Gravitational collapse in f(R) theories
TL;DR: In this article, a general f(R) model with uniformly collapsing cloud of self-gravitating dust particles is analyzed, and the authors find that the analysis of gravitational collapse is an important tool to constrain models that present late-time cosmological acceleration.

TL;DR: In this article, the Robertson-Walker Metric is used to measure the radius of the Planck Epoch in the expanding universe, which is a measure of the number of atoms in the universe.
Journal ArticleDOI
CP Violation in the Renormalizable Theory of Weak Interaction
TL;DR: In this article, it was shown that no CP-violating interactions exist in the quartet scheme without introducing any other new fields, and that the strong interaction must be chiral SU ( 4) X SU( 4) invariant as precisely as the conservation of the third component of the iso-spin.
Journal ArticleDOI
Partial Symmetries of Weak Interactions
TL;DR: In this paper, the weak and electromagnetic interactions of leptons are examined under the hypothesis that the weak interactions are mediated by vector bosons, and it is shown that the simplest partially-symmetric model reproducing the observed electromagnetic and weak interactions requires the existence of at least four vector-boson fields (including the photon).
