Sivers asymmetry extracted in SIDIS at the hard scale of the Drell-Yan process at COMPASS / Adolph, C ; Aghasyan, M ; Akhunzyanov, R ; Alexeev, M G ; Alexeev, G D ; Amoroso, A ; Andrieux, V ; Anfimov, N V ; Anosov, V ; Augsten, K et al.
Proton transverse-spin azimuthal asymmetries are extracted from the COMPASS 2010 semi-inclusive hadron measurements in deep inelastic muon-nucleon scattering in those four regions of the photon virtuality $Q^2$, which correspond to the four regions of the di-muon mass $\sqrt{Q^2}$ used in the ongoing analysis of the COMPASS Drell-Yan measurements.

Single hadron azimuthal asymmetries in the cross sections of positive and negative hadron production in muon semi-inclusive deep inelastic scattering off longitudinally polarised deuterons are determined using the 2006 COMPASS data and also all deuteron COMPASS data. [...]

We present measurements of two-particle correlations with neutral pion trigger particles of transverse momenta $8 < p_{\mathrm{T}}^{\rm trig} < 16~\mathrm{GeV}/c$ and associated charged particles of $0.5 < p_{\mathrm{T}}^{\rm assoc} < 10~\mathrm{GeV}/c$ versus the azimuthal angle difference $\Delta\varphi$ at midrapidity in pp and central Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}}=2.76$ TeV with ALICE.

Measurement of $CP$ violation in $B^0 \!\rightarrow D^+ D^-$ decays / LHCb collaboration
The $C\!P$ violation observables $S$ and $C$ in the decay channel $B^0 \!\rightarrow D^+ D^-$ are determined from a sample of proton-proton collisions at centre-of-mass energies of $7$ and $8$ TeV, collected by the LHCb experiment and corresponding to an integrated luminosity of $3~ {\text {fb}}^{-1}$.
