Abstract This Primer examines Skilling's nested sampling algorithm for Bayesian inference
and, more broadly, multidimensional integration. The principles of nested sampling are …

The hadronic width of the ground state of pionic hydrogen has been redetermined by X-ray
spectroscopy to be\varGamma^ π H _ 1s=(856\, ±\, 16_ stat\, ±\, 22_ sys) Γ 1 s π H=(856±16 …

Muon catalyzed fusion (μ CF) in which an elementary particle, muon, facilitates the nuclear
fusion between the hydrogen isotopes has been investigated in a long history. In contrast to …

Nested sampling is an efficient algorithm for the calculation of the Bayesian evidence and
posterior parameter probability distributions. It is based on the step-by-step exploration of …

The CREMA collaboration is pursuing a measurement of the ground-state hyperfine splitting
(HFS) in muonic hydrogen ($\mu $ p) with 1 ppm accuracy by means of pulsed laser …

The ground-state level shifts and broadenings of the hydrogen isotopes caused by the
strong interaction have been redetermined by using a high-resolution crystal spectrometer …

The cyclotron trap was developed at SIN/PSI to increase the stop** density of nega-tively
charged particle beams for the formation of exotic atoms in low pressure gases. A weak …

The strong-interaction effects both in pionic hydrogen and deuterium atoms have been re-
determined with improved precision. The hadronic shift and width in pionic hydrogen …
