B-Reconstruction Methods via Geometro-Kinematic Constraints (I)
  Decay channels with attractive branching ratios, or interesting physics, are recovered by substituting missing particles (nu, pi0, etc) with combined geometric and kinematic constraints. The Sliding Vertex method is shown in this part-I, for reconstructing strongly boosted B0s decays - at the LHC.
