D63 (2001) 075002 | | Subject: | hep-ph hep-ex | | Abstract: | We study the production at future $e^+e^-$ linear colliders of the heavy neutral Higgs bosons $H$ and $A$ of the minimal supersymmetric standard model in association with top and bottom quarks. The cross sections have a strong dependence on the parameter $ aneta$, and thus provide a good way to determine it. At a linear collider with $sqrt s = 0.5-1$ TeV and expected integrated luminosities, we find significant sensitivities for determining $ aneta$. In the Supergravity scenario, the sensitivity is particularly strong for $ aneta > 10$, reaching a 15% or better measurement. In the general MSSM scenario, the interplay between the $4b$ and $4t$ channels results in a good determination for $ aneta < 10$, while the sensitivity is weakened for higher values of $ aneta$. | | Source: | arXiv, hep-ph/0006223 | | Services: | Forum | Review | PDF | Favorites | |
