Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The total cross sections for the e+e– → a1π, e+e– → K1(1270)K, and e+e– → K1(1400)K processes have been calculated within the U(3) × U(3) chiral Nambu–Jona-Lasinio model. Since experimental data on these processes are absent, the reported theoretical results can be treated as predictions.
