Multi-photon decay mode spectroscopy of positronium
… for the branching ratio of the four-photon decay of parapositronium (BR4γ) was measured using a multi-gamma-ray spectrometer. For the first time in such measurements, the spectrometer consisted of an array of eight identical LaBr3:Ce scintillator detectors, each of which combines good …

Photon decay rate of sigma plus from unsubtracted dispersion relations
… we derive integral representations for the weak photon decay amplitudes Fl and F2. The integrals involve the magnetic and electric dipole amplitudes M and .1 Eo+ of the photopion production. They also involve the pion-nucleon scattering phase shifts of the states Pll, P3l, Sll and S3l , The …

A study of the photon decay modes of the giant dipole resonance in even-A neodymium isotopes
… experiment measured the elastic and inelastic photon scattering cross sections into the ground and first excited state across the isotopic chain 142,146,148,150Nd between the energies of 12 and 18 MeV, spanning the peak of the Isovector Giant Dipole Resonance. Inelastic scattering into the …

Observation and measurement of a standard model Higgs Boson-like diphoton resonance with the CMS detector
… from the search of the Higgs boson through its decay into two photons at the CMS experiment at CERN's Large Hadron Collider (LHC), on the full LHC "Run I" data collected by the CMS detector during 2011 and 2012, consisting of proton-proton collision events at [square root of] s = 7 TeV with L = …

Strong Magnetic Field Effects and Molecular Processes with Applications to White Dwarfs
… probability for the hydrogenlike 2s two-photon decay has been investigated and shown to increase substantially with field strength. The computed two-photon spectra show resonances and interference minima. Anomalous Zeeman depolarization features are found in computed two-photon …

An analysis of pion photoproduction
… analysis of pion photoproduction data up to a photon lab energy of 1.8 GeV has been performed. Both energy-dependent and energy-independent solutions have been obtained. The energy-dependent parametrization incorporates the recently determined elastic pion nucleon scattering amplitudes in such …

Quantum electrodynamics and fundamental constants
… corrections in order (Zα)² to the two-photon decay rate of ionic states are calculated, as well as the leading radiative corrections of α(Zα)² ln[(Zα)⁻²]. It is shown that the corrections is gauge-invariant under a "hybrid" gauge transformation between Coulomb and Yennie gauge.</p> …

Effiziente Erzeugung verschränkter Photonenpaare
Efficient Generation of Entangled Photon-Pairs The first experiments with correlated photons have been performed in the context of EPR-Bell experiments on the realistic and local properties of quantum mechanics. The source used there produced pairs of polarization entangled photons from a 2-photon …
