For background gauge field configurations reducible to the form AÎ¼ = (Ãƒ3, ~ A(~x)) where Ãƒ3 is a constant, we provide an elementary derivation of the recently obtained result for the exact inducedâ€¦ (More)

We report the measurement of the Cabibbo-Kobayashi-Maskawa CP-violating angle Î³ through a Dalitz plot analysis of neutral D-meson decays to K(S)(0) Ï€+ Ï€- and K(S)(0) K+ K- produced in the processesâ€¦ (More)

By applying an inverse Landau-Khalatnikov transformation, connecting (resummed) Schwinger-Dyson treatments in non-local and Landau gauges of QED 3 , we derive the infrared behaviour of theâ€¦ (More)

We report a direct measurement of D0-D0 mixing parameters through a time-dependent amplitude analysis of the Dalitz plots of D(0) â†’ K(S)(0) Ï€+ Ï€- and, for the first time, D0 â†’ K(S)(0)K+ K- decays.â€¦ (More)

In July 1925 Heisenberg published a paper [Z. Phys. 33 879-893 (1925)] which ended the period of â€˜the Old Quantum Theoryâ€™ and ushered in the new era of Quantum Mechanics. This epoch-making paper isâ€¦ (More)

A recent study of dynamical chiral symmetry breaking in N-flavour QED 3 at finite temperature is extended to include the effect of fermion wavefunction renormalisation in the Schwinger-Dysonâ€¦ (More)

We present some results about the interplay between the chiral and decon-finement phase transitions in parity-conserving QED 3 (with N flavours of massless 4 component fermions) at finiteâ€¦ (More)
