[Confinement-workshop] Reminder about title/abstract submission for the Workshop of confinement physics JLab March 12-15, 2012

[Brodsky, Stanley J.]

Dear Michael,

Happy New Year!

I look forward to seeing you at JLab in March!

Workshop on Confinement Physics
March 12-15, 2012
Jefferson Lab
Newport News, VA

Here is my title and abstract:


AdS/QCD, Light-Front Holography, and Sublimated Gluons



Gauge/gravity duality leads to a simple, analytical, and phenomenologically compelling nonperturbative approximation to the full light-front QCD Hamiltonian. This approach, called "Light-Front Holography", successfully describes the spectroscopy of light-quark meson and baryons, their elastic and transition form factors, and other hadronic properties. The bound-state Schrodinger and Dirac equations of the soft-wall AdS/QCD model predict linear Regge trajectories which have the same slope in orbital angular momentum L and radial quantum number n for both mesons and baryons. Light-front holography connects the fifth-dimensional coordinate of AdS space z to an invariant impact separation variable zeta in 3+1 space at fixed light-front time. A key feature is the determination of the frame-independent light-front wavefunctions of hadrons -- the relativistic analogs of the Schrodinger wavefunctions of atomic physics which allow one to compute form factors, transversity distributions, spin properties of the valence quarks, jet hadronization, and other hadronic observables. One thus obtains a one-parameter color-confining model for hadron physics at the amplitude level. AdS/QCD also predicts the form of a non-perturbative effective running coupling and its beta-function with an infrared fixed point which agrees with the effective coupling extracted from measurements of the Bjorken sum rule below 1 GeV^2. This is consistent with a flux-tube interpretation of QCD where soft gluons are sublimated into a color-confining potential for quarks. I will discuss a number of phenomenological hadronic properties which support this picture.

dear friends
                   first Happy New Year!

next thanks to all those who have submitted a talk title and short
abstract by the deadline of January 7th.
Can I please ask the rest of you to submit yours to replace my "made-up"
titles on the website.
Please do this as soon as possible, so I can draw up a schedule for the
meeting.

                                     very many thanks   Mike Pennington
