LENA_1981_I164397
Measurement of the charged particle multiplicities and a thrust-like variable in $\Upsilon(1S,2S)$ decays and nearby continuum. As LENA had no magnetic field the momenta of the charged particles were not measured and therefore a thrust-like variable $T^\prime$ was constructed using only the directions of the charged particles. Beam energy must be specified as analysis option "ENERGY" when rivet-merging samples.
