Bottomonia production and polarization in the NRQCD with $$k_T$$ kT -factorization. II: $$\Upsilon (2S)$$ Υ(2S) and $$\chi _b(2P)$$ χb(2P) mesons
Abstract The $$\Upsilon (2S)$$ Υ(2S) production and polarization at high energies is studied in the framework of $$k_T$$ kT -factorization approach. Our consideration is based on the non-relativistic QCD formalism for bound states formation and off-shell production amplitudes for hard partonic subpr...
