Excitation of Physical Vacuum

TL;DR

This paper proposes the concept of 'excitation of physical vacuum' to explain various anomalous experimental results in particle physics, suggesting new measurements to test this theoretical idea.

Contribution

It introduces the novel notion of vacuum excitation as an explanation for unexplained experimental phenomena in low-energy particle interactions.

Findings

Explains large sigma-term in pion-nucleon scattering

Accounts for the ΔT=1/2 rule in kaon decays

Predicts new measurements of multiparticle production and heavy virtual object decays

Abstract

Introducing such a notion as a "excitation of physical vacuum" we do an attempt to explain some strange experimental facts such as large value of $\sigma$-term measured in pion-nucleon low energy scattering, $\Delta T=1/2$ rule in kaon two pion decay modes, the ratio of strange to nonstrange yield in low energy proton-antiproton annihilation, excess of soft photons in hadron's collisions. As a test of our approach we suggest to measure the multiparticle production processes and decays of heavy virtual objects.
