Abstract
The possibility of hadronic Dark Matter particles is analised in the framework of the simplest extensions of the Standard Model. Hadronic particles possess strong interaction and consist of new heavy quark and light standard one. It is shown that the existence of heavy quarks does not contradict to the precision electro-weak restrictions on new physics. The neutral and charged pseudoscalar low-lying heavy states are considered as the Dark Matter particle and its mass-degenerated partner. We evaluated the values of their masses and lifetime of the charged component. The potential of low-energy interactions of these particles with nucleons is described in the framework of the exchangemeson model. Some peculiarities of the hadronic Dark Matter scenario are also discussed.
Highlights
The most popular candidates on Dark Matter (DM) carrier are weakly interacting massive particles (WIMP)
We consider the second and third variant of hadronic DM. It was shown in the works [19, 20], that the scenario of hadronic DM does not contradict to the electro-weak restrictions on new physics and the experimental data on abundence of anomalous elements
It was shown that the hadronic DM is not excluded by electro-weak and cosmochemical restrictions
Summary
The most popular candidates on Dark Matter (DM) carrier are weakly interacting massive particles (WIMP). Such particles are discovered not yet and there are only rigid restrictions on the cross-sections of WIMP-nucleon interactions [1]. We consider the scenario with hadronic DM particles, which is special case of SIMP one. We consider the second and third variant of hadronic DM It was shown in the works [19, 20], that the scenario of hadronic DM does not contradict to the electro-weak restrictions on new physics and the experimental data on abundence of anomalous elements now. Strong QCD-type interaction of new quark Q with ordinary one leads to the forming of coupled states - two-quark (meson) and three-quark (baryon) heavy hadrons.
