Scattering polarized electrons provides an important probe of the weak interactions. Precisely measuring the parity-violating left-right cross section asymmetry is the goal of a number of experiments recently completed or in progress. The…
Signals and backgrounds for strong $WW$ scattering at the SSC and LHC are considered. Complementarity of resonant signals in the $I=1$ $WZ$ channel and nonresonant signals in the $I=2$ \wpwp channel is illustrated using a chiral lagrangian…

Weyl semimetals (WSMs) are characterized by topologically stable pairs of nodal points in the band structure, that typically originate from splitting a degenerate Dirac point by breaking symmetries such as time reversal or inversion…
