A search for new heavy resonances decaying to pairs of bosons ($WW$, $WZ$, or $WH$) is presented. The analysis uses data from proton-proton collisions collected with the CMS detector at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of $137\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$. One of the bosons is required to be a W boson decaying to an electron or muon and a neutrino, while the other boson is required to be reconstructed as a single jet with mass and substructure compatible with a quark pair from a $W$, $Z$, or Higgs boson decay. The search is performed in the resonance mass range between 1.0 and 4.5 TeV and includes a specific search for resonances produced via vector boson fusion. The signal is extracted using a two-dimensional maximum likelihood fit to the jet mass and the diboson invariant mass distributions. No significant excess is observed above the estimated background. Model-independent upper limits on the production cross sections of spin-0, spin-1, and spin-2 heavy resonances are derived as functions of the resonance mass and are interpreted in the context of bulk radion, heavy vector triplet, and bulk graviton models. The reported bounds are the most stringent to date.

The B$^0_s$ and B$^+$ production yields are measured in PbPb collisions at a center-of-mass energy per nucleon pair of 5.02 TeV. The data sample, collected with the CMS detector at the LHC, corresponds to an integrated luminosity of 1.7 nb$^{-1}$. The mesons are reconstructed in the exclusive decay channels B$^0_s$ $\to$ J/$\psi(\mu^+\mu^-)\phi($K$^+$K$^-)$ and B$^+$ $\to$ J/$\psi(\mu^+\mu^-)$K$^+$, in the transverse momentum range 7-50 GeV/c and absolute rapidity 0-2.4. The B$^0_s$ meson is observed with a statistical significance in excess of five standard deviations for the first time in nucleus-nucleus collisions. The measurements are performed as functions of the transverse momentum of the B mesons and of the PbPb collision centrality. The ratio of production yields of B$^0_s$ and B$^+$ is measured and compared to theoretical models that include quark recombination effects.

Bottom baryons are composed of a b quark and two lighter quarks ðbqq0Þ. In the constituent quark model [1,2], such baryon states form multiplets according to the symmetries of their flavor, spin, and spatial wave functions [3]. The Λb baryon is the lightest of the bottom baryons and forms an isospin (I) singlet ðbudÞwith spin-parity JP 1⁄4 1 2 þ. Two I 1⁄4 1 triplets with JP 1⁄4 1 2 þ (Σb) and JP 1⁄4 2 (Σ b) are expected, with the spin of the flavor-symmetric qq0 diquark Sqq0 1⁄4 1. Four of those six states, the Σ b and Σ b baryons (uub and ddb), have been observed by the CDF collaboration [4,5] and reported briefly in a previous LHCb paper [6]. Beyond these ground states, radially and orbitally excited states are expected at higher masses, but only a few excited baryons have been observed in the bottom sector [7–10]. The search for and study of these states will cast light on the internal mechanisms governing the dynamics of the constituent quarks [11,12]. In this Letter, we report the observation of structures in both the Λbπ and Λbπ mass distributions (charge conjugation is implied throughout this Letter) using pp collision data collected by the LHCb experiment at ffiffi

We report on the status of the phenomenological access of gen eralized parton distributions from photon and meson electroproduction off proton. Thereby, we emphasize the role of HERMES data for deeply virtual Compton scattering, which allows us to map various asymmetries into the space of Compton form factors.

Article history: Received 8 August 2016 Received in revised form 10 November 2016 Accepted 16 November 2016 Available online 2 December 2016 Editor: L. Rolandi A search is made for the highly-suppressed B meson decays B+ → K + K +π− and B+ → π+π+ K − using a data sample corresponding to an integrated luminosity of 3.0 fb−1 collected by the LHCb experiment in proton–proton collisions at centre-of-mass energies of 7 and 8 TeV. No evidence is found for the decays, and upper limits at 90% confidence level are determined to be B(B+ → K + K +π−) < 1.1 × 10−8 and B(B+ → π+π+ K −) < 4.6 × 10−8. © 2016 The Author.

R. Aaij et al. (LHCb Collaboration) (Received 24 February 2016; published 17 June 2016) Charm meson oscillations are observed in a time-dependent analysis of the ratio ofD → Kþπ−πþπ− to D → K−πþπ−πþ decay rates, using data corresponding to an integrated luminosity of 3.0 fb−1 recorded by the LHCb experiment. The measurements presented are sensitive to the phase-space averaged ratio of doubly Cabibbo-suppressed to Cabibbo-favored amplitudes rK3π D and the product of the coherence factor RK3π D and a charm mixing parameter y 0 K3π. The constraints measured are r K3π D 1⁄4 ð5.67 0.12Þ × 10−2, which is the most precise determination to date, and RK3π D y 0 K3π 1⁄4 ð0.3 1.8Þ × 10−3, which provides useful input for determinations of the CP-violating phase γ in B → DK , D → K∓π π∓π decays. The analysis also gives the most precise measurement of the D → Kþπ−πþπ− branching fraction, and the first observation of D–D̄ oscillations in this decay mode, with a significance of 8.2 standard deviations.

High transverse momentum π-mesons have been measured with the H1 detector at HERA in deep-inelasticep scattering events at low Bjorkenx, down tox ≈ 4·10. The measurement is performed in a region of small angles with respec t to the proton remnant in the laboratory frame of reference, namely the forward region, a nd corresponds to central rapidity in the centre of mass system of the virtual photon and prot on. This region is expected to be particularly sensitive to QCD effects in hadronic final st tes. Differential cross-sections for inclusiveπ-meson production are presented as a function of Bjorkenx a d the fourmomentum transfer Q, and as a function of transverse momentum and pseudorapidit y. A recent numerical BFKL calculation and predictions from QCD models based on DGLAP parton evolution are compared with the data. To be submitted to Phys. Lett.

The triple-differential dijet cross-section, dσep/dQdEt 2 dx γ , is measured with the H1 detector at HERA as a function of the photon virtuality Q, the fraction of the photon’s momentum carried by the parton entering the hard scattering , x γ , and the square of the mean transverse energy, Et 2 , of the two highest Et jets. Jets are found using a longitudinal boost-invariantkT clustering algorithm in theγ∗p center of mass frame. The measurements cover the ranges 1.6 < Q < 80 GeV in virtuality and0.1 < y < 0.7 in inelasticityy. The results are well described by leading order QCD models wh ich include the effects of a resolved component to the virtual photon. Models which tre at the photon as point-like fail to describe the data. An effective leading order parton de sity for the virtual photon is extracted as a function of the photon virtuality, the probin g scale and the parton momentum fraction. Thexγ and probing scale dependences of the parton density show cha racteristic features of photon structure, and a suppression of this stru cture with increasingQ is seen. Submitted toEur. Phys. J.
