Second Order Twist Contributions to the Balitsky-Kovchegov Equation at Small-X: Deterministic and Stochastic Pictures
Second Order Twist Contributions to the Balitsky-Kovchegov Equation at small-x: Deterministic and Stochastic Pictures S. K. Grossberndt Department of Physics, Columbia University (Dated: January 5, 2021) I study the second order twist corrections to a toy model of a dipole-dipole interaction in the context of a both deterministic and stochastic effects. This work is done in the high NC limit in the Bjorken picture. I show that the correction to the second twist terms of the stochastic picture suggest additional importance of the second twist correction in the stochastic model as compared to the deterministic model.

In Leon's Company, It Seemed That Anything Might Be Possible

In the session entitled Honoring Leon Lederman, Sally Dawson gave an overview of Leon’s scientific career, Marge Bardeen reviewed his work in science education, and I spoke of his years as Fermilab Director.

(Fermilab Creative Services) In 1978, Leon Lederman put aside a promising career in experimental physics that had spanned three decades to accept the appointment as Director of Fermilab—the Enrico Fermi National Accelerator Laboratory. Leon was tied to Fermilab even before it existed. He had discov- ered early in life that if he took himself seriously, others were likely 1 L. M.

He gave voice to a complaint of university users that they had not been treated justly at Berkeley and Brookhaven, where the very powerful in-house groups would—according to Leon—consume all the prime beam time for themselves, and only then distribute scraps among the sorry supplicants from Columbia University and other institutions. -

The primary objective of the run, to commission and ensure stable operation of the accelerator complex and the experiments, has been achieved, and much has been learned about machine operation. The experiments succeeded in \rediscovering" the standard model of particle physics, and using familiar physics objects such as W ±, Z0, J= , Υ, jets, b-hadrons, and top-quark pairs to tune detector performance. -

Early in 2010, the LHC is projected to run at 3:5 TeV per beam, with the energy increasing later in the run to perhaps 5 TeV per beam, or beyond. The prime objective of the 2009{2010 run is to commission and ensure stable operation of the accelerator complex and the experiments. For the ex- periments, an essential task is to \rediscover" the standard model of particle physics, and to use familiar physics objects such as W ±, Z0, J= , Υ, jets, b-hadrons, and top-quark pairs to tune detector performance. -
