help in the BAW resonator with serie capacitance and negative parallel capacitance

I have a problem in the transfer function of the resonator decribed as figure 1
I will how i can know the transfer function (impedance) of the BAW resonator with serie capacitance and negative parallel capacitance
The transfer function without the serie capacitance Cs is written as:
H(s)= (Ym+s(Cp-Cc)) /[(Ym+S(Cc+Cp)+(1/Rs]
avec Ym=1/[Rm+s.Lm+(1/(s.Cm))]
I have know the final expression of the H(s) if Cc=Cp ( antiresonnace cancellation) but How I can find the transfer function H(s) with added Cs as shown in attached file.
with best regards
