[Theory-seminars] Lecture and seminar on Monday

[Christopher Thomas]

Dear all,

On Monday (March 29) we have:

* 11am (F113): Final part of the mini lecture series by Leonard Gamberg
(Penn State) on "The transverse spin and momentum structure of hadrons".

* 1pm (L104): Theory Seminar -- Eric Braaten (Ohio State) "The X(3872)
Files".

*Mini lecture series* on "The transverse spin and momentum structure of
hadrons" -- Lecture 3

Monday, March 29th
11am
Room F113

Leonard Gamberg
Penn State

Theoretical and experimental research on hard scattering processes has
resulted in a great deal of knowledge on the partonic content of hadron
structure. These talks focus on the role that transverse spin and
momentum correlations play in our understanding of the partonic
sub-structure of the hadrons in the context of QCD scattering
reactions such as semi-inclusive deep inelastic scattering.  An emphasis
is placed on the emerging role of so call naive time reversal odd
("T-odd") effects in describing these correlations in terms of parton
distribution and fragmentation functions.  I will  summarize the key
theoretical issues and discuss some experimental results that have led
us to the present understanding.

*The X(3872) Files*

Eric Braaten
Ohio State University

Many new c c-bar mesons have been discovered in recent years that lie
above the charm meson pair threshold and have properties that seem
incompatible with charmonium.  There is one whose structure can be
deduced unambiguously from the current data:  the amazing X(3872).
I will explain what the X(3872) is, but that will not answer the 
question of why it is.  I will offer some suggestions for how effective 
field theory methods might help answer that question.
