We discuss the profile of the impact-parameter dependent elastic scattering amplitude. Extraction of impact-parameter dependence from the data set with inclusion of the experimental data on elastic scattering at the LHC energies helps to reveal the asymptotics of hadron interactions. Analysis of the data clearly indicates that the impact-parameter elastic scattering amplitude exceed the black disk limit at the LHC energy 7 TeV and the inelastic overlap function reaches its maximum value at b > 0.
The process e + e − → K + K − π + π − has been studied in the center-ofmass energy range from 1500 to 2000 MeV using a data sample of 23 pb −1 collected with the CMD-3 detector at the VEPP-2000 e + e − collider. Using about 24000 selected events, the e + e − → K + K − π + π − cross section has been measured with a systematic uncertainty decreasing from 11.7% at 1500-1600 MeV to 6.1% above 1800 MeV. A preliminary study of K + K − π + π −
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
