Unparticle physics effects in (Lambda_b -> Lambda + missing energy) processes

TL;DR

This paper investigates how unparticle physics could influence the decay of Lambda_b baryons into Lambda baryons plus missing energy, focusing on polarization effects and sensitivity to unparticle parameters.

Contribution

It introduces an analysis of unparticle effects on Lambda_b decay processes, emphasizing polarization observables and parameter sensitivities, which is a novel approach in this context.

Findings

Branching ratio and polarization are sensitive to unparticle scale dimension d_U.

Polarization measurements can help constrain unparticle parameters.

Results suggest potential signatures of unparticle physics in baryon decays.

Abstract

We study unparticle physics effects in (Lambda_b -> Lambda + missing energy) decay with polarized $\Lambda_b$ and $\Lambda$ baryons. The sensitivity of the branching ratio of this decay and polarizations of (Lambda_b) and (Lambda) baryons on the scale dimension d_U and effective cut-off parameter (Lambda_U) are discussed.
