Lipa Física, Astronomía y Matemáticas Particle correlations Intensity interferometry Taking up and extending earlier suggestions, we show how two- and three-dimensional shapes of secondorderHBT correlations can be described in a multivariate Edgeworth expansion around Gaussian ellipsoids, withexpansion coefficients, identified as the cumulants of pair momentum difference q, acting as shape parameters.Off-diagonal terms dominate both the character and magnitude of shapes. Cumulants can be measured directlyand so the shape analysis has no need for fitting. 2007 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46437604 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.3A Vol.37 |
