Polarization of strange quarks is preserved to a high degree when they hadronize into Lambda baryons, as observed in Z decays at LEP. This opens up the possibility for ATLAS and CMS to use strange-quark polarization measurements as a characterization tool for new physics scenarios that produce such quarks. Measurements in ttbar samples would be useful for obtaining additional information about the polarization transfer from the strange quark to the Lambda baryon. Already with 100/fb in Run 2… 

Measuring quark polarizations at ATLAS and CMS

Being able to measure the polarization of quarks produced in various processes at the LHC would be of fundamental significance. Measuring the polarizations of quarks produced in new physics

Measuring c-quark polarization in W +c samples at ATLAS and CMS

A bstractThe process pp → W−c produces polarized charm quarks. The polarization is expected to be partly retained in Λc baryons when those form in the c-quark hadronization. We argue that it will

Measuring polarizations of bottom, charm, strange, up and down quarks in top decays

Standard Model $t\bar t$ samples in ATLAS and CMS provide an opportunity to conduct measurements of the polarization of quarks produced in top-quark decays. The bottom quarks from the $t \to W^+ b$

$O(\alpha_s)$ perturbative and nonperturbative corrections to polarized semileptonic $\Lambda_b$ decay distributions

In this paper we calculate first order radiative QCD corrections to the decay process b → cW − ( → ℓ − ¯ ν ℓ ) of a polarized bottom quark. Taking into account both the bottom and charm quark masses,

Heavy baryons as polarimeters at colliders

A bstractIn new-physics processes that produce b or c jets, a measurement of the initial b or c-quark polarization could provide crucial information about the structure of the new physics. In the

QCD analysis of unpolarized and polarized Λ-baryon production in leading and next-to-leading order

We analyze experimental data for the production ofbaryons in e + e − annihilation in terms of scale dependent, QCD evolved, � fragmentation functions. Apart from the vast majority of the data for

Search for Scalar Charm Quark Pair Production in pp Collisions at sqrt[s]=8  TeV with the ATLAS Detector.

In an R-parity-conserving minimal supersymmetric scenario in which a single scalar-charm state is kinematically accessible, and where it decays exclusively into a charm quark and a neutralino, 95% confidence-level upper limits are obtained in the scalar -charm-neutralino mass plane.

The study of the longitudinal polarization of and hyperons produced in polarized deep inelastic scattering, neutrino scattering, and in Z 0 decays allows one to access the spin dynamics of the quark

A nonperturbative parameter which measures the net transverse alignment of the light degrees of freedom in the fragmentation process is used to estimate the polarization retention of charm and bottom baryons.

Measurement of the transverse polarization of Λ and Λ¯ hyperons produced in proton-proton collisions at √s=7 TeV using the ATLAS detector

The transverse polarization of Λ and Λ¯ hyperons produced in proton-proton collisions at a center-of-mass energy of 7 TeV is measured. The analysis uses 760  μb−1 of minimum bias data collected by
