# Experimental and theoretical premises of new stable hadron existence

## TL;DR

This paper proposes a hypothesis for the existence of new stable heavy hadrons, supported by cosmic ray data and theoretical models, suggesting they do not conflict with existing cosmochemical and cosmological constraints.

## Contribution

It introduces a new hypothesis for stable heavy hadrons based on cosmic ray data and provides a theoretical framework for their interactions and potential extensions of the Standard Model.

## Key findings

- New stable heavy hadrons are compatible with existing cosmochemical data.
- Theoretical model supports strong repulsive interaction with nucleons at large distances.
- Extensions of Standard Model include new stable and metastable quarks.

## Abstract

The hypothesis of the new stable heavy hadrons existence is proposed which follows from Cosmic rays physics indirect data. It is shown that the hypothesis does not contradict Cosmochemical data, Cosmological test and the restrictions on New Physics effects. This conclusion is based on the most important property of the new hadrons - repulsion strong interaction with nucleons at large distance asymptote. This effect is substantiated theoretically in the framework of the low-energy hadron interaction model. Some extensions of Standard Model is considered where new stable and metastable quarks appear.
