  This paper examines the transverse momentum spectra of hadrons in the
multiparticle production at LHC in the framework of the Quark-Gluon String
Model (QGSM). It discusses the dependence of average pt on the masses of mesons
and baryons at the LHC energy 7 TeV. The QGSM description of the experimental
spectra of various hadrons led to the number of conclusions. I. The average
transverse momenta of baryons and mesons are growing with the hadron mass, so
for beauty hadrons, they are almost equal to the mass. II. By the product of
research, a regularity has been detected in the mass gaps between hadron
generations. 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 by
geometrical progression with the mass factor $\delta(M)$= 2.721828 III. The
baryon-meson symmetry seems broken until the mass of beauty hadrons, then the
hidden states should be more and more stable with the growth of the mass, so
the suggested sequence of hadronic states is a proper candidate for the Dark
Matter that, you know, contributes the valuable part to the mass of Universe.
The growing average transverse momenta are extrapolated with a similar
function, as for energy dependence of average baryon $p_t$, $<p_t> \propto
M^{0.1}$.
