Measurement of $\psi(2S)$ polarisation in $pp$ collisions at $\sqrt{s}=7$ TeV
The polarisation of prompt $\psi(2S)$ mesons is measured by performing an angular analysis of $\psi(2S)\rightarrow \mu^{+} \mu^{-}$ decays using proton-proton collision data, corresponding to an integrated luminosity of 1.0 fb$^{-1}$, collected by the LHCb detector at a centre-of-mass energy of 7 TeV. [...]

Coulomb branch Hilbert series and Hall-Littlewood polynomials / Cremonesi, Stefano ; Hanany, Amihay ; Mekareeya, Noppadol ; Zaffaroni, Alberto
There has been a recent progress in understanding the chiral ring of 3d $\mathcal{N}=4$ superconformal gauge theories by explicitly constructing an exact generating function (Hilbert series) counting BPS operators on the Coulomb branch. [...]

Measurement of event-plane correlations in √s_NN = 2.76 TeV lead–lead collisions with the ATLAS detector / ATLAS Collaboration
A measurement of event-plane correlations involving two or three event planes of different order is presented as a function of centrality for 7 $\mu$b$^{-1}$ Pb+Pb collision data at √s_NN = 2.76 TeV, recorded by the ATLAS experiment at the LHC. [...]

Observation of photon polarization in the $b \to s\gamma$ transition / LHCb collaboration
This Letter presents a study of the flavor-changing neutral current radiative $B^{\pm} \to K^{\pm}\pi^{\mp}\pi^{\pm}\gamma$ decays performed using data collected in proton-proton collisions with the LHCb detector at $7$ and $8\,$TeV center-of-mass energies. [...]
