• It is pointed out that inclusive distributions of π, K and η at large have the same dependence on transverse mass (m_⊥) in a wide range of m_⊥ at ISR energy. K/π and η/π ratios for the same value of m_⊥ are consistent with broken SU(3) relations derived from the tensor dominated Pomeron scheme. This idea is extended to SU(4) to derive asymptotic relations between inclusive distributions of charmed particles and non-charmed particles. From these relations we estimate dσ(pp→D^±X)/dy and dσ(pp→φ _cX)/dy of order of 1~5 μb and 10~100 nb, respectively. The consequences of sizable cross-sections for production of charmed particles are discussed in connection with lepton production at large angles in hadron-hadron scattering.
