Description

Transverse Λ polarization observed over four decades ago contradicted expec-
tations from early leading-order perturbative QCD calculations. Measurements
of Λ polarization from unpolarized pp and pA collisions have been previously
observed to increase as a function of xF and pT up to a few GeV range and
approximately independent of beam energy. Recent studies have linked polar-
ization to the process of hadronization, which describes how particular hadrons
are formed from scattered quarks and gluons. The high energy of the LHC
and the coverage and precision measurement possibilities from LHCb forward
geometry are ideal for studying hyperon polarization as a function of both pT
and xF . The status and prospects of Λ and Λ polarization measurements in pp,
pPb, Pbp, and fixed-target pNe collisions at LHCb are presented
