AbstractIn Ch. 1 - 5 we present a study of antler decay in determining dark matter mass. It was shown that the cusps and endpoints in some kinematic distributions of the antler decay at the LHC can probe the masses of the parity-odd missing energy particles as well as the intermediate particles. We extend this study into the high energy e+e− (or more generally lepton) linear collider, which will provide unambiguous center of mass frame and energy. We found new and more powerful cusp structures of new kinematic observables, possible only at the International Linear Collider (ILC). As a benchmark scenario, we study e+e− → ˜l+˜l − → l+l− ˜χ01 ˜χ01 and e+e− → ˜χ+1 ˜χ−1 → j j j j ˜χ01 Ch. 6 presents a new way to characterize turbulence through a search for conformal invariance in vorticity isolines of two-dimensional compressible turbulence. The conformal In Ch. 7 we introduce a photon correlation method for measuring components of the shear rate tensor in a turbulent soap film. The technique yields the mean shear rate s, Ch. 8 presents a computer algebra package to automatically generate particle physics Lagrangians based on group symmetries input by the user. Share
