Abstract

Recent work by Peláez, Rodas, and Ruiz de Elvira suggest that the f0(1370) structure is not well-defined. This paper investigates the description of this state in terms of a first-order K K bar tetraquark model. The model predicts the correct 0+ assignment for the f0(1370), but the calculated mass of 1079 MeV/c2 falls below the experimental range of 1200 – 1500 MeV/c2. The tetraquark description is not definitive, but it provides additional input to address the f0(1370) structure issues noted by Peláez, Rodas, and Ruiz de Elvira.
