This paper summarizes the relevant theoretical developments, outlines some ideas to improve experimental searches for free neutron-antineutron oscillations, and suggests avenues for future improvement in the experimental sensitivity.
This report, prepared for the Community Planning Study - Snowmass 2013 - summarizes the theoretical motivations and the experimental efforts to search for baryon number violation, focussing on nucleon decay and neutron-antineutron oscillations. Present and future nucleon decay search experiments using large underground detectors, as well as planned neutron-antineutron oscillation search experiments with free neutron beams are highlighted.
This paper summarizes discussions of the theoretical developments and the studies performed by the NNbarX collaboration for the 2013 Snowmass Community Summer Study.
By using fundamental units c, h, G as conversion factors one can easily transform the dimensions of all observables. In particular one can make them all ``geometrical'', or dimensionless. However this has no impact on the fact that there are three fundamental units, G being one of them. Only experiment can tell us whether G is basically fundamental.
The report summarizes the results of the activities of the Working Group on Precision Calculations for the Z Resonance at CERN during 1994.
It is assumed that three lepton families $(ν_e, e)$, $(ν_μ, μ)$, $(ν_τ, τ)$ carry charges, which are sources of electronic, muonic and tauonic massless vector particles, respectively. Various manifestations of these hypothetical photons are discussed.
This report consists of three parts. In Chapter 1 we present a brief description of the LEPTOP approach for the calculation of the radiative corrections in the Minimal Standard Model. The approach is based on the one-loop approximation with respect to the genuinely electroweak interaction for which simple explicit analytical formulae are valid. Starting from $G_μ, m_Z$ and $\barα\equiv α(m^2_Z)$ as the main input parameters, we consider all observables of the $Z$ boson decays and the mass of the $W$ boson on the same footing. The dressing with gluonic corrections is performed by using the results of calculations published by other authors. In Chapter 2 theoretical uncertainties inherent to our approach and hence to the LEPTOP computer program are analyzed. In Chapter 3 we describe the Fortran code of LEPTOP.
