Serendipity in dark photon searches


Based on "1801.04847[hep-ph]"

Abstract:"Searches for dark photons provide serendipitous discovery potential for other types of vector particles. In this paper, authors develop a framework for recasting dark photon searches to obtain constraints on more general theories, which includes a data-driven method for determining hadronic decay rates."

Steiner Triple Systems with High Chromatic Index


A Steiner triple system is a set of triples (subsets of ${1,2,dots,n}$) such that every pair is in exactly one triple. A partial parallel class in a Steiner triple system is a subset of its triples that are pairwise disjoint. The chromatic index of a Steiner triple system is the smallest number of partial parallel classes into which its blocks can be partitioned. It has been conjectured that every Steiner triple system of order $v eq 7$ has chromatic index at most $({v+3})/{2}$ when $v equiv3 mod{6}$ and at most $({v+5})/{2}$ when $v equiv 1 mod{6}$. We construct a Steiner triple system of order $v$ with chromatic index at least ...
