Nonperturbative strange sea in proton using wave functions inspired by light front holography A. Vega, I. Schmidt, T. Gutsche, V. E. Lyubovitskij

P. 87 (1-7)Abstract: We use different light-front wave functions (two inspired by the AdS/QCD formalism), together with a model of the nucleon in terms of meson–baryon fluctuations to calculate the nonperturbative (intrinsic) contribution to the s(x)−s¯(x) asymmetry of the proton sea. The holographic wave functions for an arbitrary number of constituents, recently derived by us, give results quite close to known parametrizations that appear in the literature.
