Measurement of the proton form factor by studying e+e- ?p p ¯
(American Physical Society, 2015)
Using data samples collected with the BESIII detector at the BEPCII collider, we measure the Born cross section of e+e-?pp¯ at 12 center-of-mass energies from 2232.4 to 3671.0 MeV. The corresponding effective electromagnetic ...
Observation of eta ' -> omega e(+)e(-)
(American Physical Society, 2015)
Based on a sample of ?? mesons produced in the radiative decay J/????? in 1.31×109 J/? events collected with the BESIII detector, the decay ????e+e- is observed for the first time, with a statistical significance of 8?. ...
Effects of Various Helically Angled Grinding Wheels on The Surface Roughness and Roundness in Grinding Cylindrical Surfaces
(INST ZA KOVINSKE MATERIALE I IN TEHNOLOGIE, 2015)
Grinding is generally used in the final step of machining metallic materials to achieve the necessary surface quality and dimensions. Grinding wheels with flat surfaces are commonly used in the process of grinding. However, ...
Determination of reasons for organisational silence of executive nurses
