Research on physics discussed by A.K. Alok and co-researchers

  2010 MAR 16 - (VerticalNews.com) -- "We study B (s) ->mu (+) mu (-) in the context of the R-parity violating minimal supergravity in the high-tan beta regime," scientists writing in the European Physical Journal C report.

  "We find that the lowest value of the branching ratio can go well below the present LHCb sensitivity and hence B (s) ->mu (+) mu (-) can even be invisible to the LHC. We also find that the present upper bound on Br (B (s) ->mu (+) mu (-)) puts strong constraint on the minimal supergravity parameter space," wrote A.K. Alok and colleagues.

  The researchers concluded: "The constraints become more severe if the upper bound is close to its standard model prediction."

  Alok and colleagues published their study in European Physical Journal C (B (S) ->mu (+) mu (-) decay in the R-parity violating minimal supergravity. European Physical Journal C, 2010;65(3-4):491-500).
