Anomalous Internal Pair Conversion Signaling Elusive Light Neutral Particles
Abstract. In this paper we report on a systematic search for a neutral boson in the mass range between 5 and 15 MeV/c2 in the decay of highly excited nuclei. Its signature is found a deviation in the angular correlation of the e+e− pairs from conventional internal pair conversion (IPC) resulting from of its two-body decay kinematics. With an e+e− pair-spectrometer, a number of transitions has b...
متن کاملPhoton-pair conversion into neutrinos in a strong magnetic field
A general analysis of the three-vertex loop amplitude in a strong magnetic field, based on the asymptotic form of the electron propagator in the field, is performed. In order to investigate the photonneutrino process γγ → νν̄, the vertex combinations of the scalar– vector–vector (SV V ), pseudoscalar–vector–vector (PV V ), 3–vector (V V V ), and axial-vector–vector–vector (AV V ) types are consi...
متن کاملAngular correlations in internal pair conversion of aligned heavy nuclei.
We calculate the spatial correlation of electrons and positrons emitted by internal pair conversion of Coulomb excited nuclei in heavy ion collisions. The alignment or polarization of the nucleus results in an anisotropic emission of the electron-positron pairs which is closely related to the anisotropic emission of γ-rays. However, the angular correlation in the case of internal pair conversio...
متن کاملPhoton Splitting and Pair Conversion in Strong Magnetic Fields
The magnetospheres of neutron stars provide a valuable testing ground for as-yet unverified theoretical predictions of quantum electrodynamics (QED) in strong electromagnetic fields. Exhibiting magnetic field strengths well in excess of a TeraGauss, such compact astrophysical environments permit the action of exotic mechanisms that are forbidden by symmetries in field-free regions. Foremost amo...
متن کاملElectron to Selectron Pair Conversion in a Susy Bubble
In the standard model, energy release in dense stars is severely restricted by the Pauli exclusion principle. However, if, in regions of space of high fermion degeneracy, there is a phase transition to a state of exact supersymmetry (SUSY), fermion to sfermion pair conversion followed by radiative transitions to the Bose ground state could lead to a highly collimated gamma ray burst. We calcula...
