Updated analysis of NN elastic scattering to 3 GeV
In our previous analysis of nucleon-nucleon (NN) elastic scattering data [1], the upper energy limit was extended from 2.5 to 3.0 GeV in the laboratory kinetic energy, Tp, in order to accomodate higher-energy proton-proton (pp) scattering measurements from SATURNE II at Saclay and the EDDA Collaboration at COSY. Comparisons were made with the direct amplitude reconstruction (DAR) and partial-wa...

متن کاملThe NN scattering 3 S 1 − 3 D 1 mixing angle at NNLO
The S1−D1 mixing angle for nucleon-nucleon scattering, ǫ1, is calculated to next-to-next-to-leading order in an effective field theory with perturbative pions. Without pions, the low energy theory fits the observed ǫ1 well for momenta less than ∼ 50 MeV. Including pions perturbatively significantly improves the agreement with data for momenta up to ∼ 150 MeV with one less parameter. Furthermore...
متن کاملFast k-NN search
Random projection trees have proven to be effective for approximate nearest neighbor searches in high dimensional spaces where conventional methods are not applicable due to excessive usage of memory and computational time. We show that building multiple trees on the same data can improve the performance even further, without significantly increasing the total computational cost of queries when...
متن کاملnN Backward Scattering
nN backward scattering data above 5 GeV /c are analyzed in terms of the baryon Regge pole exchange and accompanying Regge cut due to the strong absorption. The fit of the cross sections is reasonable. The role of the cut turns out to be very important: (1) The extrapolated magnitude of the L10 residue at a 4 =! is significantly larger than that without the cut. Ll0 residue with or without the w...
