It is shown that one can retain the two-component neutrino theory and time reversal with scalar and tensor interactions in the β-decay Hamiltonian, if one postulates that the scalar term produces neutrino emission and the tensor term antineutrino emission. This is consistent with all present experimental data.

Neutrino Theory

Expressions are given for the distribution of electrons emitted in the decay of aligned muons as a function of their energy, direction, and spin. The two-component neutrino theory of Yang and Lee is used, and two cases are considered: (i) neutrino and antineutrino emitted; (ii) two neutrinos emitted. Various correlation terms arise as a result of the inclusion of electron spin. Among these is a time reversal dependent term whose presence would be evinced by asymmetry in a transverse polarization of electrons emitted at right angles to the muon spin.

The Standard Model

This review paper stresses the possible connection between time-reversal violation and new physics processes beyond the standard model. In particular, this violation is proposed as an alternative to CP violation in the search for such unkown processes. Emphasis is put on the weak decays of heavy hadrons, especially beauty ones. Specific methods for extracting useful parameters from experimental data are elaborated in order to test TR symmetry. These methods could be used successfully in the analysis of the LHC data.

Solid Adsorbents

The concepts of Stoeckli as well as those of Wojsz and Rozwadowski have been adopted for describing adsorption from two-component non-electrolyte liquid mixtures at solid adsorbents taking into account structural heterogeneity of the adsorbent. Some new global adsorption equations have been obtained and verified on the basis of experimental data.

Present Experimental Data

In the recent past (PVP2013-97677, PVP2014-28197, PVP2015-45286) we had started to determine the static equivalent pressures pstat of the eight detonative pressure scenarios in long and short pipes for different detonable gas mixtures. The pstat-values are of vital importance for process design: by assigning static equivalent pressures to the highly dynamic detonative pressure peaks it is possible to apply the established pressure vessel guidelines, which can only cope with static loads, for the design of detonation pressure resistant pipes. One important finding was that the ratio R between pstat at the location where transition from deflagration to detonation occurs and pstat in the region of the stable detonation strongly depends on the reactivity of the gas mixture. In this paper we present experimental data showing the variation of R over the entire explosive range of Methane/O2/N2 mixtures. Qualitatively, the results should be representative for all other combustible/O2/N2-mixtures. Furthermore, recommendations for estimating pstat values of short pipe scenarios on basis of the long pipe scenarios are given.

Model Independent

The model-independent constraints on the Abelian Z′ couplings from the LEP data are applied to estimate the Z′ production in experiments at the Tevatron and LHC. The Z′ total and partial decay widths are analyzed. The results are compared with model-dependent predictions and present experimental data from the Tevatron. If we assume the 1–2σ hints from the LEP data to be a signal of the Abelian Z′ boson, then the Tevatron data constrain the Z′ mass between 400 GeV and 1.2 TeV.
