1107.1133 | the decay of the @xmath0 boson into supersymmetric particles is studied . we investigate how these supersymmetric modes affect the current limits from the tevatron and project the expected sensitivities at the lhc . employing three representative supersymmetric @xmath0 models , namely , @xmath1 , @xmath2 , and the sequ... | 166 |
1305.5620 | we describe numerical simulations , using the particle - in - cell ( pic ) and hybrid - pic code lsp [ t. p. hughes et al . , phys . rev . st accel . beams * 2 * , 110401 ( 1999 ) ] , of the head - on merging of two laboratory supersonic plasma jets . the goals of these experiments are to form and study astrophysically... | 234 |
hep-th0306231 | a fuzzy circle and a fuzzy 3-sphere are constructed as subspaces of fuzzy complex projective spaces , of complex dimension one and three , by modifying the laplacians on the latter so as to give unwanted states large eigenvalues . this leaves only states corresponding to fuzzy spheres in the low energy spectrum ( this ... | 108 |
0802.2945 | we measure the projected rotational velocities of the late b - type hypervelocity stars hvs7 and hvs8 from high resolution spectroscopy to be 60 @xmath0 17 km s@xmath1 and 260 @xmath0 70 km s@xmath1 . the slow rotation of hvs7 is in principle consistent with having originated in a binary system , assuming a high inclin... | 141 |
