This paper examines the transverse momentum spectra of hadrons in themultiparticle production at LHC in the framework of the Quark-Gluon StringModel (QGSM). It discusses the dependence of average pt on the masses of mesonsand baryons at the LHC energy 7 TeV. The QGSM description of the experimentalspectra of various hadrons led to the number of conclusions. I. The averagetransverse momenta of baryons and mesons are growing with the hadron mass, sofor beauty hadrons, they are almost equal to the mass. II. By the product ofresearch, a regularity has been detected in the mass gaps between hadrongenerations. This hypothesis suggests some hidden symmetrical(neither-meson-nor-baryon) neutral hadron states with the masses:0.251,0.682,1.85,5.04,13.7,37.2,101.,275.,748.... GeV, which is produced bygeometrical progression with the mass factor $\delta(M)$= 2.721828 III. Thebaryon-meson symmetry seems broken until the mass of beauty hadrons, then thehidden states should be more and more stable with the growth of the mass, sothe suggested sequence of hadronic states is a proper candidate for the DarkMatter that, you know, contributes the valuable part to the mass of Universe.The growing average transverse momenta are extrapolated with a similarfunction, as for energy dependence of average baryon $p_t$, $<p_t> \proptoM^{0.1}$.
