Comment on "Observation of a narrow structure in H-1(gamma,K-S(0))X via interference with phi-meson production"

Anghinolfi, M. et al. (2012) Comment on "Observation of a narrow structure in H-1(gamma,K-S(0))X via interference with phi-meson production". Physical Review C, 86(6), 069801:1-069801:2. (doi: 10.1103/PhysRevC.86.069801)

Abstract

In Ref. [1], the authors claim to observe a narrow structure in the mass spectrum constructed from the (pK_L) system using data from the CLAS detector. The interpretation of this narrow structure given in Ref. [1] is as follows: “It may be due to the photoproduction of the Theta+ pentaquark or some unknown Sigma∗ resonance.” The authors go on to say that “it is unlikely for the observed structure to be due to a Sigma∗ resonance.” This analysis was reviewed by the CLAS Collaboration, following the established procedures for all CLAS papers, and did not receive approval. The purpose of this Comment is to explain the reasons why that analysis was not approved for publication.
