SUSY particles

Analysis of the SUSY spectrum in supergravity unified models is given under the naturalness criterion that the universal scalar mass (m_0) and the gluino mass (m_{\tilde g}) satisfy the constraint m_0, m_{\tilde g} less than or equal to 1 TeV. The SUSY spectrum is analysed in four different scenario...

description Analysis of the SUSY spectrum in supergravity unified models is given under the naturalness criterion that the universal scalar mass (m_0) and the gluino mass (m_{\tilde g}) satisfy the constraint m_0, m_{\tilde g} less than or equal to 1 TeV. The SUSY spectrum is analysed in four different scenarios: (1) minimal supergravity models ignoring proton decay from dimension five operators, (2) imposing proton stability constraint in supergravity models with SU(5) type embedding which allow proton decay via dimension five operators, (3) with inclusion of dark matter constraints in models of type (1), and (4) with inclusion of dark matter constraint in models of type (2). It is found that there is a very strong upper limit on the light chargino mass in models of type (4), i.e., the light chargino mass is less than or equals 120 GeV.
