“…Duality has been observed both for the integral of structure functions over the whole resonance region, W < 2 GeV ("global duality"), as well as for averages over individual resonances ("local duality") [54]. Initial duality data on polarized structure functions from SLAC [37] and HERMES [55,56] have been followed by much more detailed examinations of duality in this case by experiments at Jefferson Laboratory [12,22,57], including results from a partial analysis of the present data set [16]. Reference [54] summarizes the conditions under which duality has been found to hold at least approximately.…”

“…Hence, we looked for evidence of local and global duality for 0.5 < Q 2 < 5 GeV 2 by applying duality tests to determine at what values of (Q 2 ,W ) the DIS behavior represents the average polarization response in the resonance region. A first study of duality for spin structure functions using the CLAS data for both polarized proton and deuteron targets was carried out and reported in an earlier publication [16].…”

We present the results of our final analysis of the full data set of g p 1 (Q 2 ), the spin structure function of the proton, collected using CLAS at Jefferson Laboratory in [2000][2001] We compare our final results with various theoretical models and expectations, as well as with parametrizations of the world data. Our data, with their precision and dense kinematic coverage, are able to constrain fits of polarized parton distributions, test pQCD predictions for quark polarizations at large x, offer a better understanding of quark-hadron duality, and provide more precise values of higher twist matrix elements in the framework of the operator product expansion.

“…More recently, the availability of extensive, precise structure function data from Jefferson Lab and elsewhere, over a wide range of kinematics, has opened up the possibility for in-depth studies of quark-hadron duality. Duality has now been observed in the proton F 2 and F L structure functions [7][8][9][10][11][12], the F 2 structure function of nuclei [13], the spin-dependent g 1 structure functions of the proton and 3 He [ [14][15][16], the individual helicity-1/2 and 3/2 virtual photoproduction cross sections for the proton [17], and in parity-violating electron-deuteron scattering [18].…”

Using the recently published data from the BONuS experiment at Jefferson Lab, which utilized a spectator tagging technique to extract the inclusive electron-free neutron scattering cross section, we obtain the first direct observation of quark-hadron duality in the neutron F2 structure function. The data are used to reconstruct the lowest few (N = 2, 4 and 6) moments of F2 in the three prominent nucleon resonance regions, as well as the moments integrated over the entire resonance region. Comparison with moments computed from global parametrizations of parton distribution functions suggest that quark-hadron duality holds locally for the neutron in the second and third resonance regions down to Q 2 ≈ 1 GeV 2 , with violations possibly up to 20% observed in the first resonance region.

“…II through IV can be directly extended to spin and polarization dependent structure functions. This will be important since the extraction of certain spin dependent effects can be especially sensitive to target mass effects [45][46][47][48][49][50]. We leave these interesting and important topics for future consideration.…”

What does kinematical target mass sensitivity in DIS reveal about hadron structure?

et al. 2019

View full text Add to dashboard Cite

We study the role of purely external kinematical approximations in inclusive deep-inelastic lepton-hadron scattering within QCD factorization, and consider factorization with an exact treatment of the target hadron mass. We discuss how an observed phenomenological improvement obtained by accounting for target mass kinematics could be interpreted in terms of general properties of target structure, and argue that such an improvement implies a hierarchy of nonperturbative scales within the hadron. *
