A Measurement of the Total Width, the Electronic Width and the Mass of the Upsilon(10580) Resonance

TL;DR

This paper reports precise measurements of the Upsilon(10580) resonance's total width, electronic width, and mass using data from the BABAR detector at SLAC, providing important parameters for understanding bottomonium states.

Contribution

The study provides the first precise measurements of the Upsilon(10580) resonance parameters with detailed experimental data from the BABAR detector.

Findings

Total width measured as (20.7 +- 1.6 +- 2.5) MeV

Electronic width measured as (0.321 +- 0.017 +- 0.029) keV

Mass measured as (10.5793 +- 0.0004 +- 0.0012) GeV

Abstract

We present a preliminary measurement of the resonance parameters of the Upsilon(10580) resonance with the BABAR detector at the SLAC PEP-II asymmetric B factory. We measure the total decay width to be (20.7 +- 1.6 +- 2.5) MeV, the partial electronic width to be (0.321 +- 0.017 +- 0.029) kev and the mass to be (10.5793 +- 0.0004 +- 0.0012) GeV.
