Dear Stepan,
Mark Strikman will visit JLab this week and give a seminar on perspectives in high-energy
eA physics with EIC, at the time & place of the regular EIC meeting, Friday 9:30 AM, Room F326.
The event will be informal and is intended to enable broad-based discussion of future plans.
Could you perhaps inform interested people?
Please see abstract below.
Mark Strikman (Penn State):
"Perspectives in high-energy eA physics with EIC:
Nuclear shadowing, nonlinear effects, black-disk regime"
In this talk I will focus on the electron-nucleus phenomena which lead to a nonlinear dependence
on the nucleus atomic number, A. First, unitarity considerations will be used to estimate the x-range
where the rise of the small dipole-nucleus/proton cross section should be tamed and the black-disk
regime may set in. Contrary to some expectations it is found that this regime is reached at similar x
for nuclei and proton targets, due to the presence of leading-twist nuclear shadowing. Next, the theory
of leading-twist shadowing will be reviewed, including confirmation of our prediction of large leading-twist
gluon shadowing in J/psi photoproduction at the LHC. The EIC will provide ample opportunities for detailed
studies of various phenomena related to the nuclear shadowing. Finally, we will discuss methods for
observing the breakdown of leading-twist dynamics due to the approach to the black-disk regime. We will
argue that the most promising approach is studying forward hadron production at the EIC and the LHC.
Friday January 27, 9:30 AM, Room F326
