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.
In this work, the mixing angle of the vector [Formula: see text] and [Formula: see text] mesons is estimated in the framework of Nambu–Jona-Lasinio model. The decay [Formula: see text] is considered as a basic process to determine this angle. The obtained value is compared with the results of the other authors. Besides, the width of the decay [Formula: see text] and the cross-section of the process [Formula: see text] are calculated by using this angle.
