Spin asymmetries for events with high $p_T$ hadrons in DIS and an evaluation of the gluon polarization / Adeva, B. ; Arik, E. ; Arvidson, A. ; Badelek, B. ; Baum, G. ; Berglund, P. ; Betev, L. ; Birsa, R. ; de Botton, N. ; Bradamante, F. et al.
We present a measurement of the longitudinal spin cross section asymmetry for deep inelastic muon-nucleon interactions with two high transverse momentum hadrons in the final state. Two methods of event classification are used to increase the contribution of the Photon Gluon Fusion process to above 30%. [...]

Search for Colour Singlet and Colour Reconnection Effects in Hadronic Z Decays at LEP / L3 Collaboration
A search is performed in symmetric 3-jet hadronic Z decay events for evidence of colour singlet production or colour reconnection effects. Asymmetries in the angular separation of particles are found to be sensitive indicators of such effects. [...]

Midrapidity antiproton-to-proton ratio in pp collisions at $\sqrt{s} = 0.9$ and $7$~TeV measured by the ALICE experiment / ALICE collaboration
The ratio of the yields of antiprotons to protons in pp collisions has been measured by the ALICE experiment at $\sqrt{s} = 0.9$ and $7$~TeV during the initial running periods of the Large Hadron Collider(LHC). The measurement covers the transverse momentum interval $0.45 < p_{\rm{t}} < 1.05$~GeV/$c$ and rapidity $|y| < 0.5$. [...]

A new measurement of the Collins and Sivers asymmetries on a transversely polarised deuteron target / COMPASS Collaboration
New high precision measurements of the Collins and Sivers asymmetries of charged hadrons produced in deep-inelastic scattering of muons on a transversely polarised 6LiD target are presented. The data were taken in 2003 and 2004 with the COMPASS spectrometer using the muon beam of the CERN SPS at 160 GeV/c [...]

Rapidity-Alignment and $mrm{p}_T$ Compensation of Particle Pairs in Hadronic $Z^0$ Decays / DELPHI Collaboration
Observation is made of rapidity-alignment of \KK and \pp pairs which results from their asymmetric orientation in rapidity, with respect to the direction from primary quark to antiquark. The \KK and \pp data are consistent with predictions from the fragmentation string model. [...]

Search for neutralino pair production at $\sqrt{s}$ = 189 GeV / DELPHI Collaboration
A search for pair-production of neutralinos at a LEP centre-of-mass energy of 189 GeV gave no evidence for a signal. This limits the neutralino production cross-section and excludes regions in the parameter space of the Minimal Supersymmetric Standard Model (MSSM)..

Bose-Einstein correlations in $W^{+}W^{-}$ events at LEP2 / DELPHI Collaboration
Bose-Einstein correlations (BEC) between final state particles in the reaction e+e- -> W+W- -> q_1 anti-q_2 q_3 anti-q_4 have been studied. Data corresponding to a total integrated luminosity of 550 pb^{-1}, recorded by the DELPHI detector at centre-of-mass energies ranging from 189 to 209 GeV, were analysed. [...]

Determination of $A^{b}_{FB}$ at the Z pole using inclusive charge reconstruction and lifetime tagging / DELPHI Collaboration
A novel high precision method measures the b-quark forward-backward asymmetry at the Z pole on a sample of 3,560,890 hadronic events collected with the DELPHI detector in 1992 to 2000. An enhanced impact parameter tag provides a high purity b sample [...]
