Bottomonia production and polarization in the NRQCD with $$k_T$$ kT -factorization. I: $$\Upsilon (3S)$$ Υ(3S) and $$\chi _b(3P)$$ χb(3P) mesons
Abstract The $$\Upsilon (3S)$$ Υ(3S) 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...
