"abstract": "In the context of large volume Big Divisor (nearly)\r\nSLagy D3\/D7 \u03bc-Split SUSY [1], after an explicit identification\r\nof first generation of SM leptons and quarks with fermionic superpartners\r\nof four Wilson line moduli, we discuss the identification of\r\ngravitino as a potential dark matter candidate by explicitly calculating\r\nthe decay life times of gravitino (LSP) to be greater than age of\r\nuniverse and lifetimes of decays of the co-NLSPs (the first generation\r\nsquark\/slepton and a neutralino) to the LSP (the gravitino) to be\r\nvery small to respect BBN constraints. Interested in non-thermal\r\nproduction mechanism of gravitino, we evaluate the relic abundance\r\nof gravitino LSP in terms of that of the co-NLSP-s by evaluating\r\ntheir (co-)annihilation cross sections and hence show that the former\r\nsatisfies the requirement for a potential Dark Matter candidate. We\r\nalso show that it is possible to obtain a 125 GeV light Higgs in our\r\nsetup.",
