Abstract We report the results of a search for a new vector boson ( $$ A'$$ A ′ ) decaying into two dark matter particles $$\chi _1 \chi _2$$ χ 1 χ 2 of different mass. The heavier $$\chi _2$$ χ 2 particle subsequently decays to $$\chi _1$$ χ 1

Abstract Recently, the ATOMKI experiment has reported new evidence for the excess of $$e^+e^-$$ e + e - events with a mass $$\sim $$ ∼ 17 MeV in the nuclear transitions of $$^4$$ 4 He, that they previously observed in measurements with $$^8$$ 8 Be.

A search for a new Z^{'} gauge boson associated with (un)broken B-L symmetry in the keV-GeV mass range is carried out for the first time using the missing-energy technique in the NA64 experiment at the CERN SPS. From the analysis of the data with 3.2

The intensities of 14N NQR signals have been calculated in relation to the amplitude of the initiating radiofrequency (RF) field of the radiopulse, the pulse duration, and the detuning. It is discussed whether it is possible to compensate the decreas

We discuss results on neutrino mixing in a three family scenario. We use the Open image in new window MSSM for the theoretical description of the neutrino masses. We show that one has to include the tree-level and the \(q\tilde q\) one-loop as well a

Lepton number violation (LNV) mediated by short- range operators can manifest itself in both neutrinoless double beta decay (0 nu beta beta) and in processes with same- sign dilepton final states at the LHC. We derive limits from existing LHC data at

We present analytical constraints so that the wide class of color-charge-breaking (CCB) vacua is absent in the minimal supersymmetric standard model (MSSM). We show that equal-scalar-field direction minima, which can be excluded by the well-known con

It is argued that the large-scale (>7°) cosmic microwave background anisotropy detected in the COBE cosmic experiment can be considered as a trace of the fractal structure of quantum gravity.

New constraints on the parameters of the minimal supersymmetric standard model with explicit $R$-parity violation ( ${R}_{p}$MSSM) are obtained from the current experimental lower bound on the half-life of ${}^{76}$Ge $0\ensuremath{\nu}\ensuremath{\b
