Finite Flag - Transitive An - 2 . 2 . L * . L Geometries

If F is a geometry for this rank 3 diagram and F' is its shadow geometry with respect to the central node of the diagram, then f satisfies the Intersection Property (IP), it belongs to the following diagram where L and L* denote the classes of linear spaces and dual linear spaces, respectively. According to a well established habit, we only consider residually connected and firm geometries. Tha...

MOORE GEOMETRIES AND RANK 3 GROUPS HAVING / m = l t

In view of the standard correspondence between transitive groups and certain graphs, this result can be rephrased in the following manner. Let F be a graph which is connected and not complete. Assume that G « Aut F is transitive both on ordered adjacent and non-adjacent pairs of points, and that two non-adjacent points are adjacent to exactly one point. Then T has no triangles, and G and T are ...

15 evaluate the correction term for each triple in the left side of table 1, but for brevity of exposition we will evaluate this term only for a sample of each class (T 2 and T 4).

The Decays K L → l + l − l ′ + l ′ − Revisited

The double lepton pair decay modes of the KL meson are analyzed including all contributions of order p in Chiral Perturbation Theory. The experimentally established eeee mode and the recently observed eeμμ mode are discussed in detail. Typeset using REVTEX 0 In this note we reconsider the double lepton pair decays KL → llll that were studied many years ago by Miyazaki and Takasugi [1]. The two ...
