摘要：

The paper is devoted to theoretical consideration of inclusive eta(c, b) meson production at LHC. It is shown that existing experimental data on eta(c) meson production at LHCb detector can be described in the framework of NRQCD formalism and color singlet component with phenomenological value of matrix element vertical bar R(0)vertical bar(2) gives main contribution. Using this model, we present theoretical prediction for integrated cross-sections and transverse momentum distributions for inclusive eta(c) production at other LHC detectors. The case of eta(b) meson production at LHC is also considered.
