Accessing the quark orbital angular momentum with Wigner distributions
Cedric Lorce, Barbara Pasquini
The quark orbital angular momentum (OAM) has been recognized as an important piece of the proton spin puzzle. A lot of effort has been invested in trying to extract it quantitative…
Comment on "Proton Spin Structure from Measurable Parton Distributions" by Ji, Xiong and Yuan (PRL109, 152005 (2012))
Elliot Leader, Cédric Lorcé
We show that the recent claim that the expression 1/2 \int x dx [ H_q (x,0,0) + E_q(x,0,0)], involving the generalized parton distributions H and E, measures the transverse angular…
Next-to-leading-order QCD corrections to the yields and polarisations of J/Psi and Upsilon directly produced in association with a Z boson at the LHC
Bin Gong, Jean-Philippe Lansberg, Cedric Lorce +1
We update the study of the production of direct J/Psi in association with a Z boson at the Next-to-Leading Order (NLO) in alpha_s by evaluating both the yield differential in P_T a…
Wilson lines and orbital angular momentum
Cédric Lorcé
We present an explicit realization of the Chen et al. approach to the proton spin decomposition in terms of Wilson lines, generalizing the light-front gauge-invariant extensions di…
Wigner distributions and quark orbital angular momentum
Cedric Lorce, Barbara Pasquini
We discuss the quark phase-space or Wigner distributions of the nucleon which combine in a single picture all the information contained in the generalized parton distributions and…
Geometrical approach to the proton spin decomposition
Cédric Lorcé
We discuss in detail and from the geometrical point of view the issues of gauge invariance and Lorentz covariance raised by the approach proposed recently by Chen et al. to the pro…
