The ALICE Collaboration reports the measurement of semi-inclusive distributions of charged-particle jets recoiling from a high transverse momentum (high p_{T}) hadron trigger in proton-proton and central Pb-Pb collisions at sqrt[s_{NN}]=5.02 TeV. A data-driven statistical method is used to mitigate the large uncorrelated background in central Pb-Pb collisions.

It is also an indicator of the early modernization of Bulgarian society in the first half of the twentieth century. Using the example of Vakarel in Middle Western Bulgaria, the authors define servantry as a social mediator, facilitating the spread of urban culture and European models in the Shopluk villages around the capital Sofia.

Measurements of K^{+}K^{-} photoproduction probe the couplings between the ϕ(1020) and charged kaons with photons and nuclear targets. The kaon-proton scattering occurs at energies far above those available elsewhere.
