The relevance of positivity in spin physics
J. Soffer, X. Artru, M. Elchikh +2
Positivity reduces substantially the allowed domain for spin observables. We briefly recall some methods used to determine these domains and give some typical examples for exclusiv…
How is transversity related to helicity for quarks and antiquarks inside the proton?
C. Bourrely, F. Buccella, J. Soffer
We consider the quark and antiquark transversity distributions inside a polarized proton and we study how they are expected to be related to the corresponding helicity distribution…
Why the Real Part of the Proton-Proton Forward Scattering Amplitude Should be Measured at the LHC
C. Bourrely, N. N. Khuri, A. Martin +2
For the energy of 14 TeV, to be reached at the Large Hadron Collider (LHC), we have had for some time accurate predictions for both the real and imaginary parts of the forward prot…
Positivity constraints on photon structure functions
K. Sasaki, J. Soffer, T. Uematsu
We investigate the positivity constraints for the structure functions of both virtual and real photon. From the Cauchy-Schwarz inequality we derive three positivity conditions for…
A statistical approach for polarized parton distributions
C. Bourrely, J. Soffer, F. Buccella
A global next-to-leading order QCD analysis of unpolarized and polarized deep-inelastic scattering data is performed with parton distributions constructed in a statistical physical…
Positivity constraints and flavor dependence of higher twists
J. Soffer, O. V. Teryaev
The positivity bound for the transverse asymmetry may be improved and applied for each quark flavor separately. We use it to test the consistency of twist-two approximation f…
