The helicity density matrix elements $\rho_{00}$
of $\rho(770)^{\pm}$
and $\omega(782)$
mesons produced in Z
$^0$
decays have been measured using the OPAL detector at LEP. Over the measured meson energy range, the values are compatible with 1/3, corresponding to a statistical mix of helicity $-1$
, 0 and +1 states. For the highest accessible scaled energy range 0.3 $<$
$x_E$
$<$
0.6, the measured $\rho_{00}$
values of the $\rho^{\pm}$
and the $\omega$
are 0.373 $\pm$
0.052 and 0.142 $\pm$
0.114, respectively. These results are compared to measurements of other vector mesons.read more

Spin alignment of vector mesons in non-central A+A collisions
TL;DR: In this article, the effect of global polarization of the produced quarks in non-central heavy-ion collisions on the spin alignment of vector mesons is discussed and the alignment is quite different for different hadronization scenarios.
Journal ArticleDOI
Partial wave analysis of two hadron fragmentation functions
TL;DR: In this paper, the authors considered the option of extracting the transversity distribution by using interference fragmentation functions into two leading hadrons inside the same current jet and derived new positivity bounds on them.

Evidence for a Transverse Single-Spin Asymmetry in Leptoproduction of pi+pi- Pairs
TL;DR: In this article, a single-spin asymmetry was measured in the azimuthal distribution of pi+pi pairs produced in semi-inclusive deep-inelastic scattering on a transversely polarized hydrogen target.
Journal Article
Probing the transverse spin of quarks in deep inelastic scattering
TL;DR: In this paper, it is shown that transversity can be measured in the above processes, in connection with three different fragmentation functions: the first one requires the observation of an unpolarized final state hadron with transverse momentum (Collins function), the second requires the interference between the s-and p-wave production of two hadrons, and the third requires the observed p-waving two-hadron production, or equivalently of a spin-one resonance.
Journal ArticleDOI
Isospin Symmetry of Fragmentation Functions
TL;DR: In this article, the authors make a systematic study of the isospin symmetry of fragmentation functions by taking decay contributions into account, and show that in the unpolarized case, the symmetry is held for fragmentation functions of Λ and only tiny violations are allowed for other hadrons such as nucleon and pions due to the contributions from weak decays.
