Measurements of the Momentum Spectrum of  -Mesons at Sea Level I: The Momentum Range 5   10⁸eV/C-2   10¹⁰eV/C

A compilation of high energy atmospheric muon data at sea level

“…Next to fitting the normalization, we also calculated the normalization by comparing the integrated flux above 10 GeV/c (or the lower cutoff of the experiment whichever is higher) to an integrated flux calculation using the reference shape. The data published in references [13], [16] and [15] do not allow for this normalization method. As these papers are normalized [27] 10/6 0.822 ± 0.009 0.818 ± 0.007 Kremer 1997 data [27] 13/6 0.831 ± 0.008 0.821 ± 0.007 Table 1: Normalization of datasets with respect to the Bugaev calculation to Rossi [28] we recalculate this normalization point with the reference shape.…”

“…13) Spectrum: no absolute flux determination, only normalization to previous measurements by other experiments. Charge ratio: A few measurements are given with slightly asymmetric errors; they have been 'symmetrized' by shifting the central value to the center of the error interval.…”
