Heavy quarkonium production in hadronic collisions in TMD framework

Heavy quarkonium ($\Upsilon$) production at low transverse momentum ($P_\perp$) in high-energy hadronic collisions is revisited from the point of view of transverse momentum dependent (TMD) framework. We perform resummation of double logarithmic correction associated with initial-state soft gluon shower for $b\bar b$ production by employing Collins-Soper-Sterman (CSS) formalism. We show that the CSS formalism provides a nice description of $\Upsilon$ production data in p+$\rm\bar{p}$ collisions at Tevatron and p+p collisions at the LHC.Comment: 6 pages, 2 figures, proceedings of QCD Evolution 2017, 22-26 May 2017, Newport News, VA-US

Some Results on the Boundary Control of Systems of Conservation Laws

This note is concerned with the study of the initial boundary value problem for systems of conservation laws from the point of view of control theory, where the initial data is fixed and the boundary data are regarded as control functions. We first consider the problem of controllability at a fixed time for genuinely nonlinear Temple class systems, and present a description of the set of attainable configurations of the corresponding solutions in terms of suitable Oleinik-type estimates. We next present a result concerning the asymptotic stabilization near a constant state for general $n\times n$ systems. Finally we show with an example that in general one cannot achieve exact controllability to a constant state in finite time.Comment: 10 pages, 4 figures, conferenc

ESC NN-Potentials in Momentum Space. II. Meson-Pair Exchange Potentials

The partial wave projection of the Nijmegen soft-core potential model for Meson-Pair-Exchange (MPE) for NN-scattering in momentum space is presented. Here, nucleon-nucleon momentum space MPE-potentials are NN-interactions where either one or both nucleons contains a meson-pair vertex. Dynamically, the meson-pair vertices can be viewed as describing in an effective way (part of) the effects of heavy-meson exchange and meson-nucleon resonances. From the point of view of ``duality,'' these two kinds of contribution are roughly equivalent. Part of the MPE-vertices can be found in the chiral-invariant phenomenological Lagrangians that have a basis in spontaneous broken chiral symmetry. It is shown that the MPE-interactions are a very important component of the nuclear force, which indeed enables a very succesful description of the low and medium energy NN-data. Here we present a precise fit to the NN-data with the extended-soft-core (ESC) model containing OBE-, PS-PS-, and MPE-potentials. An excellent description of the NN-data for $T_{Lab} \leq 350$ MeV is presented and discussed. Phase shifts are given and a $\chi^2_{p.d.p.} = 1.15$ is reached.Comment: 27 pages, 5 PostScript figures, revtex

Conflict of Deciding Zero Point Kilometer on Islamic Entrance in Indonesian Archipelago (Critical Discourse Analysis with Norman Fairclough Approach)

Critical discourse analysis (CDA) in this research came from two texts of online news. They were Medan Business Daily from Medan, North Sumatera and Kabar Pidie Jaya from Pidie, Aceh. Both of the news had the same theme, that was legitimation zero point kilometer of Islamic entrance in Indonesian archipelago. However, both of the news was conflicated, if it had not been finished as soon as possible, it would be a long conflict. Because of that, this CDA had a purpose to try for giving solution from another point of view. The point of view was from historical data about differences of point of view on the online news. The method of this study was by using Norman Fairclough approach with text analysis (description), discourse practice (interpretation), and social practice (explanation). The result of text analysis (description) was analyzed by using rhetoric pattern; modality, such as akan, bisa; positive sentences; negative sentences; interrogative sentences; experiential and attitudinal vocabularies; life metaphor. Discourse practice analysis (interpretation) such as event series from the two online news texts. Explanative analysis followed the situational change, institution change, and social-cultural change which would be mediating this conflict based on the historical facts. Copyright (c) 2017 by KARSA.

Pressure dependence of diffusion coefficient and orientational relaxation time for acetonitrile and methanol in water: DRISM/mode-coupling study

We present results of theoretical description and numerical calculation of the dynamics of molecular liquids based on the Reference Interaction Site Model / Mode-Coupling Theory. They include the temperature-pressure(density) dependence of the translational diffusion coefficients and orientational relaxation times for acetonitrile and methanol in water at infinite dilution. Anomalous behavior, i.e. the increase in mobility with density, is observed for the orientational relaxation time of methanol, while acetonitrile does not show any deviations from the usual. This effect is in qualitative agreement with the recent data of MD simulation and with experimental measurements, which tells us that presented theory is a good candidate to explain such kind of anomalies from the microscopical point of view and with the connection to the structure of the molecules.Comment: 10 pages, 2 eps-figures, 3 table
