    Undergrad D meson decay and invariant mass

    Considering a D0->π+K- where the D meson decays from rest. If one was to want to calculate the invariant mass of the D meson by measuring the momenta of the pion and kaon, following from conservation of momentum: m2=(Eπ+EK)2-(pπ+pK)2 However by inputting numerical data Eπ=137MeV EK=493MeV...
