An explicit example is presented (a one-loop triangle graph) where dimensional regularization fails to regulate the infra-red singularities that emerge at intermediate steps of studying large-Q Sudakov factorization. The mathematical nature of the phenomenon is explained within the framework of the theory of the As-operation. E-mail address: [email protected]. On leave from Institute for Nuc...
These proceedings are based on lectures given at the Helmholtz International Summer School Heavy Quark Physics at the Bogoliubov Laboratory of Theoretical Physics, Dubna, Russia, during August 2008. I review the current status of CP violation in B meson decays from the B factories. These results can be used, along with measurements of the sides of the Unitarity Triangle, to test the CKM mechani...

O wning Natural resources has been beneficial for some Countries, but hurtful for some others. Optimum management of natural resources in the former group has enhanced economic growth, bad governance, however, has led to Dutch Disease in the latter group. Bad governance in Iran has created Dutch Disease, Rentier State, and Resource Curse, DRR as a characteristic triangle. As the Iran...
According to its historical background, natural conditions and political geography, Caucasus is made up of a variety of races, followers and cultures of different rituals and religions. Historical links of Caucasus residents with Iranian civilization and culture resulted in their adherence to Iranian governments in equilibrium with Roman, Ottoman and Russian policies. Following the collapse of ...
A recent lower bound on the number of edges in a k-critical nvertex graph by Kostochka and Yancey yields a half-page proof of the celebrated Grötzsch Theorem that every planar triangle-free graph is 3-colorable. In this paper we use the same bound to give short proofs of other known theorems on 3-coloring of planar graphs, among whose is the Grünbaum-Aksenov Theorem that every planar with at mo...
The title compound, C26H20N6BrRu(BF4), crystallizes in the centrosymmetric space group P2(1)/n and consists of discrete complex units. The Ru(II) ion is octahedrally coordinated to one 2,2':6',2"-terpyridine (tpy), one 2-(phenylazo)pyridine (azpy) and a Br atom in trans-axial position at a distance of 2.547(5)A. The shorter Ru-N (azo) distance (1.960(3)A) than the Ru-N(py) distance (2.061(3)A) ...
