Understand

We present a search for a neutral, long-lived particle $L$ that is produced in $e^+e^-$ collisions and decays at a significant distance from the $e^+e^-$ interaction point into various flavor combinations of two oppositely charged tracks.

The analysis uses an $e^+e^-$ data sample with a luminosity of $489.1 \rm{fb}^{-1}$ collected by the BaBar detector at the $\Upsilon$(4S), $\Upsilon$(3S), and $\Upsilon$(2S) resonances and just below the $\Upsilon$(4S).
Fitting the two-track mass distribution in search of a signal peak, we do not observe a significant signal, and set 90% confidence level upper limits on the product of the $L$ production cross section, branching fraction, and reconstruction efficiency for six possible two-body $L$ decay modes as a function of the $L$ mass.
The efficiency is given for each final state as a function of the mass, lifetime, and transverse momentum of the candidate, allowing application of the upper limits to any production model.
