Some Practical Applications of Dark Matter Research

Singlet 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...

‌قید‌های تک Z روی مدل ماده‌ تاریک فرمیونی با واسطه شبه اسکالر در LHC

In this research we study the Mono-Z signature along with dark matter production at the LHC in a renormalizable dark matter model. We look at processes with L+L-+MET in the final state. We simulate signal and background events at central mass energy 14 TeV We then evaluate the LHC sensitivities for some points in the model parameter space for two integrated luminosities L=100 fb-1 and L=1 ab-1 ...

Bulgarian Grid, Bulgarian Virtual Observatory and Some Astronomical Applications

The development of the Bulgarian GRID, new possibilities for Bulgarian Virtual Observatory and some basic astronomical GRID applications from the published papers and internet are reviewed. Amongst the basic applications are N_body simulations, looking for dark matter, dark energy and neutrino, large scale structure of the Universe, stellar and galaxy evolution, active processes on the Sun, nea...

Formation 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...
