Study of φ(2170) at BESIII

Abstract

The strangeonium state φ(2170) is studied and presented. The processes of e +e − → K+K−, e +e − → K0 SK0 L, e +e − → φK+K− /K+K−K+K−, e +e − → φη, e +e − → φη0 , e +e − → K+K−π 0π 0 and e +e − → ωη are investigated. And the cross sections are measured precisely in the center-of-mass (c.m.) energy region from 2.00 to 3.08 GeV. The parameters of φ(2170) have been extracted from the lineshapes where applicable
