About this document
Tetraquark Mesons in Large-N QCD Analysis by sarthorks is a document available to read on EtoBox.
This document discusses tetraquark mesons in the context of quantum chromodynamics with a large number of colors N. It argues that contrary to previous conclusions, tetraquarks are not ruled out in this limit. There can exist both short-lived tetraquarks with decay rates proportional to N, and long-lived tetraquarks with decay rates proportional to 1/N. Examples of each variety are the broad f0(500) and narrow f0(980), respectively.
