CBBN in the CMSSM

, 2007
Catalyzed big bang nucleosynthesis (CBBN) can lead to an overproduction of ^6Li in gravitino dark matter scenarios in which the lighter stau is the lightest Standard Model superpartner.

Maya records of planetary conjunctions in Dresden Codex [PDF]

Serbian Astronomical Journal
Old Mayas designed a very complicated calendar, and they also recorded important historical events and astronomical phenomena. Dresden Codex (DC), one of the four preserved Mayan hieroglyphic literal legacies, contains many of these, covering ...

The causal relationship between patent growth and growth of GDP with quarterly data in the G7 countries: cointegration, ARDL and error correction models [PDF]

This empirical study investigates the dynamic link between patent growth and GDP growth in G7 economies. ARDL model showed that there exist positive relationship in long run between quarterly growth of patents and quarterly GDP growth.

The effect of gluon condensate on holographic heavy quark potential

, 2009
The gluon condensate is very sensitive to the QCD deconfinement transition since its value changes drastically with the deconfinement transition. We calculate the gluon condensate dependence of the heavy quark potential in AdS/CFT to study how the ...

Space and population – competitiveness determinants of countries in the age of globalization

Management, 2018
In the 21st century in a globalized world the level of competitiveness depends on numerous factors. This article concentrates deliberations on several of them, including space, population and international exchange.

Bouncing Universe with Quintom Matter

, 2007
The bouncing universe provides a possible solution to the Big Bang singularity problem. In this paper we study the bouncing solution in the universe dominated by the Quintom matter with an equation of state (EoS) crossing the cosmological constant ...

Is Noncommutative Eternal Inflation Possible?

, 2007
We investigate the condition for eternal inflation to take place in the noncommutative spacetime. We find that the possibility for eternal inflation's happening is greatly suppressed in this case.

Hadronic decays from the lattice

, 2006
I review the lattice QCD approach to determining hadronic decay transitions. Examples considered include rho to pi pi; b_1 to pi omega; hybrid meson decays and scalar meson decays. I discuss what lattices can provide to help understand the composition of

On the energy deposited by a quark moving in an N=4 SYM plasma

, 2007
We evaluate the energy momentum tensor of a massive quark as it moves through an N=4 SYM quark gluon plasma at constant velocity. We find that in the near-quark region, where the dynamics is expected to be dominated by dissipative behavior, the energy ...
