Infrared Renormalization Group Flow for Heavy Quark Masses
Andre H. Hoang, Ambar Jain, Ignazio Scimemi +1
A short-distance heavy quark mass depends on two parameters, the renormalization scale mu controlling the absorption of ultraviolet fluctuations into the mass, and a scale R contro…
Two-loop Jet-Function and Jet-Mass for Top Quarks
Ambar Jain, Ignazio Scimemi, Iain W. Stewart
We compute the two-loop heavy quark jet-function in the heavy quark limit. This is one of the key ingredients in next-to-next-to-leading order (NNLO) and next-to-next-to-leading-lo…
Penguin Loops for Nonleptonic B-Decays in the Standard Model: Is there a Penguin Puzzle?
Ambar Jain, Ira Z. Rothstein, Iain W. Stewart
We compute standard model penguin amplitudes in nonleptonic B-decays to light charmless mesons using tree amplitude data to fix hadronic parameters. The leading calculation is carr…
