Decoding Wheat Endosphere–Rhizosphere Microbiomes in Rhizoctonia solani–Infeste...
Araujo, R; Dunlap, C; Barnett, S; Franco, CThe endosphere and the rhizosphere are pertinent milieus with microbial communities that perturb the agronomic traits of crop plants through beneficial or detrimental interactions. In this study, we challenged these communities by adding Streptomyces biocontrol strains to wheat seeds in soils with severe Rhizoctonia solani infestation. Wheat plants were grown in a glasshouse standardized system, and the bacteri...
Azimuthal asymmetries of charged hadrons produced in high-energy muon scatterin...
COMPASS collaboration (225 authors); Bordalo, P; Franco, C; Nunes, A S; Quaresma, M; Quintans, C; Ramos, S; Silva, L; Stolarski, MSingle hadron azimuthal asymmetries in the cross sections of positive and negative hadron production in muon semi-inclusive deep inelastic scattering off longitudinally polarised deuterons are determined using the 2006 COMPASS data and also all deuteron COMPASS data. For each hadron charge, the dependence of the azimuthal asymmetry on the hadron azimuthal angle $\phi$ is obtained by means of a five-parameter fi...
Resonance Production and $\pi\pi$ S-wave in $\pi^- + p \rightarrow \pi^- \pi^- ...
COMPASS collaboration (210 authors); Bordalo, P; Franco, C; Nunes, A S; Quaresma, M; Quintans, C; Ramos, S; Silva, L; Stolarski, MThe COMPASS collaboration has collected the currently largest data set on diffractively produced π-π-π+ final states using a negative pion beam of 190 GeV/c momentum impinging on a stationary proton target. This data set allows for a systematic partial-wave analysis in 100 bins of three-pion mass, 0.5<m3π<2.5 GeV/c2, and in 11 bins of the reduced four-momentum transfer squared, 0.1<t′<1.0 (GeV/c)2. This two-...
Sivers asymmetry extracted in SIDIS at the hard scales of the Drell–Yan process...
COMPASS collaboration (225 authors); Bordalo, P; Franco, C; Nunes, A S; Quaresma, M; Quintans, C; Ramos, S; Silva, L; Stolarski, MEight proton transverse-spin-dependent azimuthal asymmetries are extracted in four regions of the photon virtuality Q2 from the COMPASS 2010 semi-inclusive hadron measurements in deep inelastic muon–nucleon scattering. These Q2 regions correspond to the four regions of the di-muon mass Q2 used in the ongoing analyses of the COMPASS Drell–Yan measurements, which allows for a future direct comparison of the nucle...
Longitudinal double spin asymmetries in single hadron quasi-real photoproductio...
COMPASS collaboration (210 authors); Bordalo, P; Franco, C; Nunes, A S; Quaresma, M; Quintans, C; Ramos, S; Silva, L; Stolarski, MWe measured the longitudinal double spin asymmetries $A_{LL}$ for single hadron muo-production off protons and deuterons at photon virtuality $Q^2$ < 1(GeV/$\it c$)$^2$ for transverse hadron momenta $p_T$ in the range 0.7 GeV/$\it c$ to 4 GeV/$\it c$ . They were determined using COMPASS data taken with a polarised muon beam of 160 GeV/$\it c$ or 200 GeV/$\it c$ impinging on polarised $\mathrm{{}^6LiD}$ or $\mat...
Collins and Sivers asymmetries in muonproduction of pions and kaons off transve...
COMPASS collaboration (209 authors); Bordalo, P; Franco, C; Nunes, A S; Quaresma, M; Quintans, C; Ramos, S; Silva, L; Stolarski, MMeasurements of the Collins and Sivers asymmetries for charged pions and charged and neutral kaons produced in semi-inclusive deep-inelastic scattering of high energy muons off transversely polarised protons are presented. The results were obtained using all the available COMPASS proton data, which were taken in the years 2007 and 2010. The Collins asymmetries exhibit in the valence region a non-zero signal for...
Search for exclusive photoproduction of Z$_c^{\pm}$(3900) at COMPASS
COMPASS collaboration (209 authors); Bordalo, P; Franco, C; Nunes, Ana Sofia; Quaresma, M; Quintans, C; Ramos, S; Silva, L; Stolarski, MA search for the exclusive production of the Zc±(3900) hadron by virtual photons has been performed in the channel Zc±(3900)→J/ψπ± . The data cover the range from 7 GeV to 19 GeV in the centre-of-mass energy of the photon–nucleon system. The full set of the COMPASS data set collected with a muon beam between 2002 and 2011 has been used. An upper limit for the ratio BR(Zc±(3900)→J/ψπ±)×σγN→Zc±(3900)N/σγN→J/ψN of...
Transverse target spin asymmetries in exclusive $\rho^0$ muoproduction
COMPASS collaboration (213 authors); Bordalo, P; Franco, C; Nunes, A.S; Quaresma, M; Quintans, C; Ramos, S; Silva, L; Stolarski, MExclusive production of $\rho^0$ mesons was studied at the COMPASS experiment by scattering 160 GeV/$c$ muons off transversely polarised protons. Five single-spin and three double-spin azimuthal asymmetries were measured as a function of $Q^2$, $x_{Bj}$, or $p_{T}^{2}$. The $\sin \phi_S$ asymmetry is found to be $-0.019 \pm 0.008(stat.) \pm 0.003(syst.)$. All other asymmetries are also found to be of small magn...
Changes in mice whole saliva soluble proteome induced by tannin-enriched diets.
Lamy, E; Graça, G; da Costa, G; Franco, C; Capela e Silva, F; Baptista, E; Coelho, AVBackground Previous studies suggested that dietary tannin ingestion may induce changes in mouse salivary proteins in addition to the primarily studied proline-rich proteins (PRPs). The aim of the present study was to determine the protein expression changes induced by condensed tannin intake on the fraction of mouse whole salivary proteins that are unable to form insoluble tannin-protein complexes. Two-dimensio...
