0802.0611 | the wide - field high - resolution infrared telescope ( white ) will be dedicated in the first years of its life to carrying out a few ( well focused in terms of science objectives and time ) legacy surveys . white would have an angular resolution of @xmath0 homogeneous over @xmath1 sq . deg . in the wavelength range @... | 280 |
hep-ph9506409 | we calculate limits on the trilinear soft - breaking parameter , @xmath0 , in the minimal supersymmetric standard model by requiring the absence of nonzero top squark vacuum expectation values . assuming a low @xmath1 , which implies a large top yukawa coupling , we also calculate one - loop corrections to the effectiv... | 127 |
