M-I coupling scales and energy dumping

BFKL Equation , Running Coupling and Renormalization Scales

I examine the solution of the BFKL equation with NLO corrections relevant for deep inelastic scattering. Particular emphasis is placed on the part played by the running of the coupling. It is shown that the solution factorizes into a part describing the evolution in Q, and a constant part describing the input distribution. The latter is infrared dominated, being described by a coupling which gr...

Competition and unilateral dumping

This paper presents an analysis of the effects of market structure on the propensity of firms to dump goods. The analysis of Brander and Krugman is extended to show that in the presence of transportation costs, bilateral intra-industry trade is not possible without dumping. Contrary to the conventional wisdom, this paper finds that firms in markets with a large number of domestic competitors ar...

Mass Scales in String and M-theory †

I review the relations between mass scales in various string theories and in M-theory. I discuss physical motivations and possible consistent realizations of large volume compactifications and low string scale. Large longitudinal dimensions, seen by Standard Model particles, imply in general that string theory is strongly coupled unless its tension is close to the compactification scale. Weakly...
