# Precise measurement of $\Sigma$ beam asymmetry for positive pion photoproduction on the proton from 550 to 1100 MeV

Abstract : Informetrics, the mathematical and statistical study of information processes, is a new promising field of research in information science. Advantages but also pitfalls and misuses of mathematics and statistics in social sciences are presented. A selection of applications (mono and multidimensionnal) coming from mathematical informetrics and statistical informetrics illustrate the efficiency of these methods.
