Implications of a charged-current anomaly at HERA
We demonstrate that in the presence of mixing between different scalar leptoquark multiplets it is possible to simultaneously account for the HERA high-$Q^2$ neutral current anomaly, and produce a charged current anomaly of comparable magnitude. The reduced branching ratio to electrons and jets of t...

| description | We demonstrate that in the presence of mixing between different scalar leptoquark multiplets it is possible to simultaneously account for the HERA high-$Q^2$ neutral current anomaly, and produce a charged current anomaly of comparable magnitude. The reduced branching ratio to electrons and jets of the lightest leptoquark state results in a significant weakening of the CDF/D0 limits on scalar leptoquarks; masses consistent with the HERA neutral current excess are comfortably within the allowed range. We show that the possibilities for such a successful mixed leptoquark scenario are quite limited, and we investigate some aspects of their phenomenology. |
