A possibility of CPT violation in the Standard Model

TL;DR

This paper explores the theoretical possibility of CPT symmetry violation within the Standard Model without contradicting established theorems, suggesting more precise experiments are needed to detect such effects.

Contribution

It proposes a scenario where CPT violation could occur in the Standard Model, challenging the common understanding and encouraging more accurate experimental tests.

Findings

CPT violation may occur without contradicting the CPT theorem

Proposes increasing measurement precision for proton-antiproton mass difference

Highlights the need for experimental verification of CPT symmetry

Abstract

It is shown that there is a possibility of violation of CPT symmetry in the Standard Model which does not contradict to the famous CPT theorem. To check this possibility experimentally it is necessary to increase the precision of measurements of the proton and antiproton mass difference by an order of magnitude
