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...
متن کاملNN Scattering Problem
It is shown that chiral perturbation theory (in its original form by Wein-berg) can describe N N scattering with positive as well as negative effective range. Some issues connected with unnaturally large N N 1 S 0 scattering length are discussed. The chiral perturbation theory approach to the low-energy purely pionic processes [1] has been generalised for processes involving an arbitrary number...
