“…By substituting the decay widths ( 24), ( 25), ( 26), (27), and ( 28) into the Breit-Wigner resonant formula (34) one can reproduce the result for the FeynCalc straightforward calculation of the total cross sections (29), (30), (31), and (32). That cross-check was used in order to validate our analytical calculations.…”

“…In particular, the typical scenarios and the regarding thermal target associated with dark boson mediators include spin-0, spin-1 and spin-2 particles such as the hidden Higgs boson [13][14][15][16][17][18][19], the dark photon [20][21][22][23][24][25][26][27][28][29][30][31][32], and the dark graviton [33][34][35][36][37][38][39][40][41][42][43][44][45], respectively. Also, in the mass range of light DM from few MeV to GeV the fixed-target experiments combine the advantages of high-energy particle beam and its relative large intensity.…”

We discuss the thermal target curves of Majorana, Dirac, scalar and vector light dark matter (DM) that are associated with the freeze-out mechanism via the annihilation into 𝑒 + 𝑒 − pair through the electron-specific spin-0 mediator of dark matter. We also discuss the mechanism to produce the regarding DM mediator in the electron (positron) fixed-target experiments such as NA64e and LDMX. We derive the corresponding experimental reaches of the NA64e and LDMX that are complementary to the DM thermal target parameter space.
