The silicon photonics field is advancing rapidly, with many new devices demonstrated recently [1]. Demonstrations have shown significantly improved performance that is now approaching that of devices on native InP substrates. In addition to the many passive devices, including AWGs, isolators, and circulators, active devices including lasers, modulators, amplifiers and photodetectors (Fig. 1) ar...

The transverse momentum distribution of W bosons at hadron colliders is well described by a parton-shower model for small p⊥ values, but not for large ones. This article is an attempt to give a better description of the distribution by using corrections derived from the matrix-element formalism. The parton shower for qq → W has been modified to resemble the matrix elements of qq → gW and qg → q...
