Unitarity limits on the mass and radius of dark-matter particles.

چکیده
Using partial wave unitarity and the observed density of tile Universe, we show that a stable elementary particle which was once in thermal equilibrium cannot have a mass greater than 340 TeV. An extended object which was once in thermal equilibrium cannot have a radius less than 7.5 x 10 -7 fro. A lower limit to the relic abundance of such particles is also found. O

Search for dark matter produced in association with a Higgs boson
This article reports on a search for dark matter pair production in association with a Higgs boson decaying to a pair of bottom quarks, using data from 20.3 fb−1 of pp collisions at a center-of-mass energy of 8 TeV collected by the ATLAS detector at the LHC. The decay of the Higgs boson is reconstructed as a high-momentum bb̄ system with either a pair of small-radius jets, or a single large-radi...
متن کاملFormation of Large Structures in the Acceleration Universe with a Hybrid Expansion Law
In the current paper, we have studied the effect of dark energy on for-mation where dark energy exists in the background. For this purpose, we used both WMAP9 and Planck data to study how the radius changes with redshift in these mod-els. We used different data sets to fix the cosmological parameters to obtain a solution for a spherical region under collapse. The mechanism of structure formation f...
متن کاملLocal dark matter clumps and the positron excess
It has been proposed that the excess in cosmic ray positrons, at approximately 8GeV, observed on both flights of the HEAT balloon experiment may be associated with the annihilation of supersymmetric (SUSY) dark matter particles in the Milky Way halo. In this paper we show how the presence of local dark matter substructure could account for this excess. Specifically, we concentrate on dark matte...
متن کاملSinglet scalar dark matter in noncommutative space
In this paper, we examine the singlet scalar dark matter annihilation to becoming the Standard Model particles in the non-commutative space. In the recent decades, many candidates of dark matter have been offered, but our information about the nature of dark matter is still limited. There are such particle candidates as scalar matetr, fermion, boson, gauge boson, etc.; however, they have nei...
متن کاملPhoton and Graviton Mass Limits
Efforts to place limits on deviations from canonical formulations of electromagnetism and gravity have probed length scales increasing dramatically over time. Historically, these formulations have passed through three stages: (1) Testing the power in the inverse-square laws of Newton and Coulomb, (2) Seeking a nonzero value for the rest mass of photon or graviton, (3) Considering more degrees o...
