[Theory-seminars] Seminar today

[Alexei Prokudin]

Dear all,

we have a Theory Center Seminar today, 3d of December,
CEBAF Center, Room L104
1:00 p.m.

Speaker: Vicent Mateu Barreda (MIT)

Title: Hadron mass effects to event shape power corrections

Abstract:
In my talk I will address the issue of mass effects on power correction 
to event shape distributions. In particular I will define an operator 
that describes the effect of hadron masses on the leading 1/Q power 
correction. Here, Q is the scale of the hard collision. Despite the fact 
that different event shapes have different hadron mass dependence, we 
provide a simple method to identify universality classes of event shapes 
whose power corrections depend on a common non perturbative parameter. 
We compute the anomalous dimension of the transverse velocity operator, 
which causes the power correction to exhibit non-trivial dependence on Q.
