    Single- and double-differential cross-section measurements are presented for the production of top-quark pairs, in the lepton + jets channel at particle and parton level. Two topologies, resolved and boosted, are considered and the results are presented as a function of several kinematic variables characterising the top and $t\bar{t}$ system and jet multiplicities. The study was performed using data from pp collisions at centre-of-mass energy of 13 TeV collected in 2015 and 2016 by the ATLAS detector at the CERN Large Hadron Collider (LHC), corresponding to an integrated luminosity of 36 fb$^{−1}$. Due to the large $t\bar{t}$ cross-section at the LHC, such measurements allow a detailed study of the properties of top-quark production and decay, enabling precision tests of several Monte Carlo generators and fixed-order Standard Model predictions. Overall, there is good agreement between the theoretical predictions and the data. Covariance matrix between the Relative double-differential cross-section as function of $m^{t\bar{t}}$ vs $|y^{t\bar{t}}|$ in 0.4 < $|y^{t\bar{t}}|$ < 0.8 and the Relative double-differential cross-section as function of $m^{t\bar{t}}$ vs $|y^{t\bar{t}}|$ in 0.4 < $|y^{t\bar{t}}|$ < 0.8 at particle level in the resolved topology, accounting for the statistical and systematic uncertainties.

    DESY-HERA, Cross sections for the production of D*+- mesons in deep inelastic e-p scattering are measured for exchanged photon virtualities, Q^2, the range 5-1000 GeV^2. The data sample from electron/positron -proton collisions at a centre-of-mass enefgy of 318 GeV, with an integrated luminosity of 363 pb-1, is used to determine the differential cross sections as functions of several variables, pt^2, eta, x, y and Q**2. The cross sections are then used to extract the chram contribution to the proton structure function, expressed in terms of the reduced charm cross section. Reduced cross section as a function of X for Q^2 = 32 GeV^2.

    This dataset corresponds to global map of built-up areas expressed in terms of a probability grid at 10 m spatial resolution derived from a Sentinel-2 global image composite (GHS_composite_S2_L1C_2017-2018_GLOBE_R2020A_UTM_10_v1_0) for reference year 2018. It builds on a new Deep Learning framework for pixel-wise large-scale classification of built-up areas named GHS-S2Net (GHS stands for Global Human Settlements, S2 refers to the Sentinel-2 satellite).

  • Authors: STAR Collaboration;

    We determine rapidity asymmetry in the production of charged pions, protons, and antiprotons for large transverse momentum ($p_{T}$) for $d+Au$ collisions at $\sqrt{s_{NN}}=200$ GeV. The rapidity asymmetry is defined as the ratio of particle yields at backward rapidity ($Au$ beam direction) to those at forward rapidity ($d$ beam direction). The identified hadrons are measured in the rapidity regions $|y| < 0.5$ and $0.5 < |y| < 1.0$ for the $p_{T}$ range $2.5 < p_{T} < 10$ GeV/c. We observe significant rapidity asymmetry for charged pion and proton + antiproton production in both the rapidity regions. The asymmetry is larger for $0.5 < |y| < 1.0$ than for $|y| < 0.5$ and is almost independent of particle type. The measurements are compared to various model predictions employing multiple scattering, energy loss, nuclear shadowing, saturation effects, and recombination and also to a phenomenological parton model. We find that asymmetries are sensitive to model parameters and show model preference. The rapidity dependence of $\pi^{-} / \pi^{+}$ and $\bar{p} / p$ ratios in peripheral $d+Au$ and forward neutron-tagged events are used to study the contributions of valence quarks and gluons to particle production at high $p_{T}$. High transverse-momentum rapidity asymmetry factor ($Y_{\scriptsize{\mbox{Asym}}}$) for $\pi^{+}+\pi^{-}$ and $p+\bar{p}$ for $|y| < 0.5$ and $0.5 < |y| < 1.0$ for minimum bias $d+Au$ collisions at $\sqrt{s_{NN}}=200$ GeV. For comparison the inclusive charged hadron results from STAR [5] are also shown by the curves.

    These data represent the fourth in a series of data collection efforts begun in 1972 to gather information on the careers and political perspectives of the delegates to the Democratic and Republican National Conventions. Respondents were asked questions regarding their political participation and preferences, life histories, political goals and expectations, and affiliations with various groups in society. The dataset also documents delegates' attitudes toward political actors such as Jimmy Carter, Ted Kennedy, Ronald Reagan, George Bush, Walter Mondale, Jesse Jackson, Michael Dukakis, Al Gore, Bob Dole, and Jack Kemp, among many others. Attitudes toward the women's movement, the moral majority, gay rights groups, abortion, environmentalists, business interests, defense, and minorities are among the issues also investigated. ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection: Performed consistency checks.; Standardized missing values.; Performed recodes and/or calculated derived variables.; Checked for undocumented or out-of-range codes.. Delegates to the 1988 Republican and Democratic National Conventions and respondents to CONVENTION DELEGATE STUDY, 1980: [UNITED STATES] (ICPSR 8367) and CONVENTION DELEGATE STUDY, 1984: [UNITED STATES] (ICPSR 8967).
