Support for "big science" must come from a society that is scientifically literate. We get few chances to develop scientific literacy for students who do not study science formally in university or college. QuarkNet provides activities in which high school students work with particle physics data and do scientific investigations. Evaluation data show that participants broaden their frame of...

As High-Energy physics is going global, high-energy physicists and their organizations collaborate more and more not only into science but also in communicating about it.
Communications play an increasing role in our society, and we face big challenges as the visibility of our field is becoming high. Networks for outreach and communications are then crucial to promote the field in a coherent...

The International Particle Physics Outreach Group (IPPOG) has developed an educational activity that brings the excitement of cutting-edge particle physics research into the classroom.
Each year, since 2005, thousands of high school students in many countries all over the world come to nearby universities or research centres for one day in order to unravel the mysteries of particle physics...

We demonstrate social media in action along with a panel discussion on how you could benefit from using these platforms to better engage with your audiences. Social media are increasingly used as tools for science communication by science journalists and writers, by scientific organisations and laboratories, as well as by scientists themselves. These media offer many advantages over...

We review the present landscape of heavy-quarkonium theory, its tests by worldwide collider and fixed-target experiments, and the future perspectives offered by the LHC. Special emphasis is placed on the effective quantum field theory of nonrelativistic QCD (NRQCD), endowed with the factorization theorem conjectured by Bodwin, Braaten, and Lepage, which arguably constitutes the most probable...

We present a rigorous next-to-leading order analysis of J/psi yield and polarization within the factorization theorem of nonrelativistic QCD (NRQCD). To the orders considered, this framework depends on the values of three color-octet long-distance matrix elements (LDMEs), which are predicted to be process-independent. We extract their values in a global fit to inclusive J/psi production yield...

Studies of quarkonia production in the forward region provide important tests of perturbative QCD. We present studies of the production of charmonia and bottomonia in the LHCb detector, using data from proton-proton collisions at a range of centre-of-mass energies. The results are compared to recent theoretical predictions. Absolute and relative production cross-sections are presented for...

The polarizations of the Upsilon(1S), Upsilon(2S) and Upsilon(3S) mesons produced in proton-proton collisions at = 7 TeV are measured using a data sample collected with the CMS detector at the LHC, corresponding to an integrated luminosity of around 5 fb^{-1}. The measurements are based on the analysis of the dimuon decay angular distributions, analyzed in three different polarization...

The production of Quarkonia states at hadron colliders has been the subject of various theoretical approaches, which can now be compared to measurement performed at LHC. In the Charmonium family, the production of J/Psi has been studied over wide range of pT. In the Bottomonium family, the production of Y(1S) has been
studied by ATLAS. The recent first observation of resonances decaying to...

I will discuss the impact of QCD corrections on the P_T differential cross section for quarkonium production at RHIC [1], Tevatron and LHC energies [2], as well as the contributions from charm-gluon fusion [3]. I will discuss the promising agreement between the parameter-free predictions of the Colour-Singlet Model --up to alpha_s^5 in some cases-- and the first LHC data for J/psi and Upsilon...

The main focus of the HERMES experiment at DESY was the detailed investigation of the spin structure of the nucleon, mainly its decomposition into contributions from quarks and gluon spins and their orbital angular momenta. Many exciting, unexpected results have been obtained by measuring semi-inclusive and exclusive processes in deep-inelastic scattering.
Over recent years, pioneering...

The study of gluon radiation in QCD, in the limit of small ("soft") momentum, remains an active research area, with a variety of phenomenological and theoretical applications. Soft gluon emission leads to large logarithms in perturbation theory which have to be summed up to all orders in the coupling, and also governs the structure of infrared singularities. Recently, new techniques and...

The exclusive photoproduction reaction gamma p -> Upsilon(1S) p has been studied with the ZEUS detector in ep collisions at HERA.The exclusive electroproduction of two pions in the mass range 0.4 < M(pipi) < 2.5 GeV has also been studied with the ZEUS detector at HERA. The two-pion invariant-mass distribution is interpreted in terms of the pion electromagnetic form factor, |F(M(pipi)|,...

The transversity distribution function, which describes the quark transverse polarization inside a transversely polarized nucleon, is the least known leading-twist component of the QCD description of the partonic structure of the nucleon. Transversity can be extracted from semi-inclusive deep-inelastic-scattering data where, however, it couples to a new fragmentation function, called the...

The BABAR Collaboration has an intensive program of studying hadronic cross sections at low-energy e+e- collisions, accessible at BaBar via initial-state radiation. Our measurements allow significant improvements in the precision of the predicted value of the muon anomalous magnetic moment. These improvements are necessary for shedding light on the current ~3.5 sigma difference between the...

We report QCD studies of pseudoscalar meson pair production in two-photon collisions at the Belle experiment. Differential cross sections have been measured for $\pi^+ \pi^-$, $\pi^0 \pi^0$, $K^+ K^-$, $K_S K_S$, $\eta \pi^0$ and $\eta \eta$ final states. Their $W$ dependence and angular distributions are compared with perturbative and non-perturbative QCD predictions at $(2.4-3.1)\ {\rm GeV}...
