    The 2HDMa model is one of the main models used in the Dark Matter searches at the LHC. So far, all the 2HDMa benchmarks used by the LHC experiments feature a Type-II Yukawa sector with degenerate Higgses ($m_A=m_H=m_{H^{\pm}}$). The latter implies, together with the fact that flavour observables put lower bounds on the mass of the charged Higgses, that the $A/H/H^{\pm}$ bosons are all...

    Recasting is an extremely powerful tool to derive limits on new physics
    models. With so many NP models at our disposal, recasting makes it easy to use the limits derived on certain models by experimental searches, to
    constrain any model of our choice. However, this method can fail, if
    the model of our interest not only differs from the one it is being
    recasted from, in terms of event...
