Its kinematic dependence of the Feynman $x_F$ and the $M_{pV}$ mass is discussed in terms of diffractive production of baryon resonances in competition with central production. The $M_{p\omega}$ spectrum has a rich structure, indicating the importance of baryon resonances decaying into $p\omega$, in sharp contrast to the structureless $M_{p\phi}$ spectrum. Outside the resonant region, the OZI violation factor is about 8, independently of $x_F$.The spin density matrix element $\rho_{00}$ of the vector mesons is studied in selected reference frames. Dependences of the vector meson spin alignment on $x_F$ and $M_{pV}$ are found. 000291944 536__ $$0G:(DE-HGF)POF3-611$$a611 - Fundamental Particles and Forces (POF3-611)$$cPOF3-611$$fPOF III$$x0 000291944 588__ $$aDataset connected to DataCite, INSPIRE 000291944 650_7 $$2autogen$$aspin: alignment 000291944 650_7 $$2autogen$$ap: beam 000291944 650_7 $$2autogen$$abaryon resonance: production 000291944 650_7 $$2autogen$$aspin: density matrix 000291944 650_7 $$2autogen$$aIizuka-Okubo-Zweig rule: violation 000291944 650_7 $$2autogen$$across section: ratio: measured 000291944 650_7 $$2autogen$$ahydrogen: liquid: target 000291944 650_7 $$2autogen$$adiffraction: production 000291944 650_7 $$2autogen$$avector meson 000291944 650_7 $$2autogen$$aCOMPASS 000291944 650_7 $$2autogen$$aspectrometer 000291944 650_7 $$2autogen$$akinematics 000291944 650_7 $$2autogen$$astructure 000291944 650_7 $$2autogen$$aFeynman 000291944 693__ $$0EXP:(DE-MLZ)NOSPEC-20140101$$5EXP:(DE-MLZ)NOSPEC-20140101$$eNo specific instrument$$x0 000291944 7001_ $$0P:(DE-HGF)0$$aCOMPASS Collaboration$$b1$$eCollaboration Author 000291944 773__ $$a10.3204/DESY-PROC-2014-04/36 000291944 7870_ $$0PUBDB-2015-03603$$aSchmidt, Alexander et.al.$$dHamburg : Deutsches Elektronen-Synchrotron, DESY, Hamburg, 2014$$iIsPartOf$$rDESY-PROC-2014-04$$tProceedings, 20th International Conference on Particles and Nuclei (PANIC 14) 000291944 8564_ $$uhttps://bib-pubdb1.desy.de/record/291944/files/36.pdf$$yOpenAccess 000291944 8564_ $$uhttps://bib-pubdb1.desy.de/record/291944/files/36.gif?subformat=icon$$xicon$$yOpenAccess 000291944 8564_ $$uhttps://bib-pubdb1.desy.de/record/291944/files/36.jpg?subformat=icon-1440$$xicon-1440$$yOpenAccess 000291944 8564_ $$uhttps://bib-pubdb1.desy.de/record/291944/files/36.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000291944 8564_ $$uhttps://bib-pubdb1.desy.de/record/291944/files/36.jpg?subformat=icon-640$$xicon-640$$yOpenAccess 000291944 8564_ $$uhttps://bib-pubdb1.desy.de/record/291944/files/36.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000291944 909CO $$ooai:bib-pubdb1.desy.de:291944$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 000291944 9131_ $$0G:(DE-HGF)POF3-611$$1G:(DE-HGF)POF3-610$$2G:(DE-HGF)POF3-600$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bForschungsbereich Materie$$lMaterie und Universum$$vFundamental Particles and Forces$$x0 000291944 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000291944 9201_ $$0I:(DE-H253)ATLAS-20120731$$kATLAS$$lLHC/ATLAS Experiment$$x0 000291944 9201_ $$0I:(DE-H253)CMS-20120731$$kCMS$$lLHC/CMS Experiment$$x1 000291944 9201_ $$0I:(DE-H253)UNI_EXP-20120731$$kUNI/EXP$$lUni Hamburg / Experimentalphysik$$x2 000291944 980__ $$acontrib 000291944 980__ $$aVDB 000291944 980__ $$aUNRESTRICTED 000291944 980__ $$aintrep 000291944 980__ $$aI:(DE-H253)ATLAS-20120731 000291944 980__ $$aI:(DE-H253)CMS-20120731 000291944 980__ $$aI:(DE-H253)UNI_EXP-20120731 000291944 9801_ $$aUNRESTRICTED 000291944 9801_ $$aFullTexts
