Sneutrino-antisneutrino oscillation at the Tevatron

TL;DR

This paper explores how sneutrino-antisneutrino oscillations at the Tevatron can serve as a probe for lepton number violation, especially in scenarios with very small decay widths and tiny mass splittings.

Contribution

It introduces a scenario where small decay widths enable detection of tiny mass splittings through sneutrino-antisneutrino oscillations at the Tevatron.

Findings

Potential to observe oscillations with mass splitting as small as 10^{-14} GeV.

Highlights the significance of small decay widths for detecting lepton number violation.

Proposes experimental signatures for future searches at the Tevatron.

Abstract

Sneutrino-antisneutrino oscillation can be a very useful probe to look for signatures of lepton number violation ($\Delta L=2$) at the Tevatron. Here, we discuss a scenario where the total decay width of the sneutrino is very small, producing interesting signals at the Tevatron for a mass splitting $\Delta m$ as small as $10^{-14}$ GeV between the sneutrino mass eigenstates.
