Leptoquark explanation of HERA anomaly in the context of gauge unification

الأصل · EN

We examine the consequences of leptoquark explanation of HERA anomaly in the context of R parity conserving supersymmetric gauge unified theory with the gauge unification scale at 10¹⁶ GeV. We pointed out the difficulty of constructing a grandunified theory. However gauge unification is still possible at 10¹⁶ GeV when additional multiplets are introduced. We determine the mass spectrum of these additional fields (fermions and scalars) in gauge mediated and supergravity scenarios. Unique signatures and mass bounds are discussed.
