Available in PDF, EPUB and Kindle. Book excerpt: The study of the transition region in the description of exclusive processes and hadron structure, from the nucleon-meson degrees of freedom in meson-exchange models at low energy to the quark-gluon degrees of freedom in pQCD at high energy, is essential for us to understand the strong interaction. The differential cross section measurements for exclusive reactions at fixed center-of-mass angles enable us to investigate the constituent counting rule, which explicitly connects the quark-gluon degrees of freedom to the energy dependence of differential cross sections. JLab Experiment E94-104 was carried out in Hall A with two high resolution spectrometers. It included the coincidence cross section measurement for the ?n --> ?-[p] process with a deuterium target and the singles measurement for the ?p --> ?+[n] process with a hydrogen target. The untagged real photons were generated by the electron beam impinging on a copper radiator. The photon energies ranged from 1.1 to 5.5 GeV, corresponding to the center-of-mass energies from 1.7 to 3.4 GeV. The pion center-of-mass angles were fixed at 50 deg, 70 deg, 90 deg, and also 100 deg, 110 deg at a few energies. The JLab E94-104 data presented in this thesis contain four interesting features. The data exhibit a global scaling behavior for both ?- and ?+ photoproduction at high energies and high transverse momenta, consistent with the constituent counting rule and the existing ?+ photoproduction data. This implies that the quark-gluon degrees of freedom start to play a role at this energy scale. The data suggests possible substructure of the scaling behavior, which might be oscillations around the scaling value. There are several possible mechanisms that can cause oscillations, for example the one associated with the generalized constituent counting rule involving quark orbital angular momentum. The data show an enhancement in the scaled cross section at center-of-mass energy near 2.2 GeV, where baryon resonances are not as well known as those at low energies. The differential cross section ratios for exclusive ?n --> ?-[p] to ?p --> ?+[n] process at ?cm = 90 deg start to show consistency with the prediction based on one-hard-gluon-exchange diagrams at high energies.

Available in PDF, EPUB and Kindle. Book excerpt: The [gamma]n [yields] [pi][sup -]p and [gamma]p [yields] [pi][sup +]n reactions are essential probes of the transition from meson-nucleon degrees of freedom to quark-gluon degrees of freedom in exclusive processes. The cross sections of these processes are also, advantageous, for the investigation of oscillatory behavior around the quark counting prediction, since they decrease relatively slower with energy compared with other photon-induced processes. Moreover, these photoreactions in nuclei can probe the QCD nuclear filtering and color transparency effects. In this talk, I discuss the preliminary results on the [gamma]p [yields] [pi][sup +]n and [gamma]n [yields] [pi][sup -]p processes at a center-of-mass angle of 90[sup o] from Jefferson Lab experiment E94-104. I also discuss a new experiment in which singles [gamma]p [yields] [pi][sup +]n measurement from hydrogen, and coincidence [gamma]n [yields] [pi][sup -]p measurements at the quasifree kinematics from deuterium and [sup 12]C for photon energies between 2.25 GeV to 5.8 GeV in fine steps at a center-of-mass angle of 90[sup o] are planned. The proposed measurement will allow a detailed investigation of the oscillatory scaling behavior in photopion production processes and the study of the nuclear dependence of rather mysterious oscillations with energy that previous experiments have indicated. The various nuclear and perturbative QCD approaches, ranging from Glauber theory, to quark-counting, to Sudakov-corrected independent scattering, make dramatically different predictions for the experimental outcomes.

Download or read book Nuclear Pion Photoproduction written by Anton Nagl and published by Springer. This book was released on 2013-10-03 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photoproduction of pions from complex nuclei has become an investigative tool for (1) the detailed form of the elementary photopion amplitude, (2) the pion-nucleus optical potential, (3) nuclear structure, and (4) off-shell and medium effects on the elementary amplitude in nuclear processes. In this book, all these aspects are considered in detail. With improved experimental accuracy and beam tech- nology the study of nuclear pion photoproduction will break new ground and become an even more powerful investigative tool. This monograph is intended as an introductory guide as well as a reference manual for grad- uate students and researchers working in this important area of physics.
