The Magnetic Field

The leptonic decay of the charged pion in the presence of background magnetic fields is investigated using quenched Wilson fermions. It is demonstrated that the magnetic field opens up a new channel for this decay. The magnetic field-dependence of the decay constants for both the ordinary and the new channel is determined. Using these inputs from QCD, we calculate the total decay rate perturbatively.

Axial Form

Axial form-factor of the radiative decay of charged pion is calculated using QCD sum rules method for non-diagonal correlator. For the ratio γ=FA(0)/FV(0) we find γ=0.6±0.15.

Neutrino Pair

The evolution of the entangled muon–neutrino system emerging from charged pion decay is explored both in vacuum and in matter. The study is based on a Weisskopf–Wigner type wave-packet description. Explicit formulas are derived displaying modulation and attenuation of the oscillations due to additional time scales characterizing the production process. The case of neutrinos disentangled due to the detection of the muon is also considered.
