Prompt atmospheric neutrinos in the quark–gluon string model
Abstract We calculate the atmospheric flux of prompt neutrinos, produced in decays of the charmed particles at energies beyond 1 TeV. Cross sections of the D mesons and $${\Lambda }^{+}_{c}$$ Λc+ baryons production in pA and $$\pi A$$ πA collisions are calculated in the phenomenological quark–gluon...

| Summary: | Abstract We calculate the atmospheric flux of prompt neutrinos, produced in decays of the charmed particles at energies beyond 1 TeV. Cross sections of the D mesons and $${\Lambda }^{+}_{c}$$ Λc+ baryons production in pA and $$\pi A$$ πA collisions are calculated in the phenomenological quark–gluon string model (QGSM) which is updated using recent measurements of cross sections of the charmed meson production in the LHC experiments. A new estimate of the prompt atmospheric neutrino flux is obtained and compared with the limit from the IceCube experiment, and with predictions of other charm production models. |
