Q–Dependence of the Gerasimov-Drell-Hearn Sum Rule
We test the Gerasimov-Drell-Hearn (GDH) sum rule numerically by calculating the total photon absorption cross sections σ1/2 and σ3/2 on the nucleon via photon excitation of baryon resonances in the constituent quark model. A total of seventeen, low-lying, non-strange baryon resonances are included in this calculation. The transverse and longitudinal interference cross section, σ 1/2, is found t...
متن کاملGravitons and the Drell-Hearn-Gerasimov Sum Rule
One-loop diagrams containing a graviton provide a finite contribution to the anomalous magnetic moment al of a lepton, whether or not the graviton propagates in n large extra compact dimensions. In the present work, the tree graph photoproduction of a graviton, integrated up to an arbitrary cutoff, is shown to violate the Drell-Hearn-Gerasimov sum rule for al . The possibility of resurrecting t...
متن کاملThe Drell - Hearn - Gerasimov Sum - Rule in QCD
Photoproduction spin sum-rules offer a new window on the spin structure of the nucleon that complements the information we can learn from polarised deep inelastic scattering experiments. We review the theory and present status of the Drell-Hearn-Gerasimov sum-rule in QCD, emphasising the possible relation between the present " discrepancy " in this sum-rule and the nucleon's strangeness magneti...
متن کاملSaturation of the Drell-Hearn-Gerasimov sum rule reexamined.
The Drell-Hearn-Gerasimov sum rule for the forward spin-flip amplitude of nucleon Compton scattering is decomposed into separate sum rules originating from different isospin components of the electromagnetic current. The resulting sum rules are reexamined using recently available analyses of single pion photoproduction in the region up to photon laboratory energies of 1.2 GeV. All three sum rul...
متن کاملOn the Gerasimov - Drell - Hearn sum rule for the deuteron
The Gerasimov-Drell-Hearn sum rule is evaluated for the deuteron by explicit integration up to a photon energy of 550 MeV including contributions from the photodisintegration channel and from coherent and incoherent single pion production as well. The photodisintegration channel converges fast enough in this energy range and gives a large negative contribution, essentially from the 1 S 0 resona...
