Title: Measurements of $$\pi^-$$ production in $^7$Be+$^9$Be collisions at beam momenta from 19$$A$$ to 150$$A$$GeV/$$c$$ in the NA61/SHINE experiment at the CERN SPS

Abstract

The NA61/SHINE collaboration studies at the CERN Super Proton Synchrotron (SPS) the onset of deconfinement in hadronic matter by the measurement of particle production in collisions of nuclei with various sizes at a set of energies covering the SPS energy range. This paper presents results on inclusive double-differential spectra and mean multiplicities of $$\pi^{-}$$ mesons produced in the 5% most central $^7$Be + $^9$Be collisions at beam momenta of 19$$A$$, 30$$A$$, 40$$A$$, 75$$A$$ and 150$$A$$ GeV/$$c$$ obtained by the so-called $h^-$ method which does not require any particle identification. The shape of the transverse mass spectra differs from the shapes measured in central Pb + Pb collisions and inelastic p + p interactions. The normalized width of the rapidity distribution decreases with increasing collision energy and is in between the results for inelastic nucleon-nucleon and central Pb + Pb collisions. The mean multiplicity of pions per wounded nucleon in central $^7$Be + $^9$Be collisions is close to that in central Pb + Pb collisions up to 75$$A$$GeV/$$c$$. However, at the top SPS energy the result is close to the one for inelastic nucleon-nucleon interactions. The results are discussed in the context of predictions for the onset of deconfinement at the CERN SPS collision energies.

Transverse momentum and rapidity spectra were obtained.

The transverse mass spectra of $$K^{*}(892)^0$$ mesons and other particles previously reported by NA61/SHINE were fitted within the Blast-Wave model. The transverse flow velocities are close to 0.1–0.2 of the speed of light and are significantly smaller than the ones determined in heavy nucleus-nucleus interactions at the same beam momenta.</span><a href='#' onclick='$(this).hide().prev().hide().prev().show();return false;' style='margin-left:10px;display:none;'>« less</a></div><div class="metadata-links small clearfix text-muted" style="margin-top:15px;"> <div class="pure-menu pure-menu-horizontal pull-right" style="width:unset;"> <ul class="pure-menu-list"> <li class="pure-menu-item"><span class="item-info-ftlink"><a class="misc doi-link " href="https://doi.org/10.1140/epjc/s10052-022-10281-5" target="_blank" rel="noopener" title="Link to document DOI" data-ostiid="1841393" data-product-type="Journal Article" data-product-subtype="AM" >https://doi.org/10.1140/epjc/s10052-022-10281-5</a></span></li> <li class="pure-menu-item"><span class="item-info-ftlink"><a class="misc fulltext-link " href="/pages/servlets/purl/1841393" title="Link to document media" target="_blank" rel="noopener" data-ostiid="1841393" data-product-type="Journal Article" data-product-subtype="AM" >Full Text Available</a></span></li> </ul> </div> </div> </div> <div class="clearfix"></div> </div> </li> <li> <div class="article item document" itemprop="itemListElement" itemscope itemtype="http://schema.org/WebPage"><meta itemprop="position" content="3" /><div class="item-info"> <h2 class="title" itemprop="name headline"><a href="/biblio/1367907-measurements-pi-pm-pm-bar-text-spectra-proton-proton-interactions-text-gev-gev-na61-shine-spectrometer-cern-sps-na61-shine-collaboration" itemprop="url">Measurements of $$$$\pi ^\pm $$$$ π ± , K $$$$^\pm $$$$ ± , p and $$$${\bar{\text {p}}}$$$$ p ¯ spectra in proton-proton interactions at 20, 31, 40, 80 and 158  $$$$\text{ GeV }/c$$$$ GeV / c with the NA61/SHINE spectrometer at the CERN SPS: The NA61/SHINE Collaboration</a></h2> <div class="metadata"> <small class="text-muted" style="text-transform:uppercase;display:block;line-height:2.5em;">Journal Article</small><span class="authors"> <span class="author">Aduszkiewicz, A.</span> ; <span class="author">Ali, Y.</span> ; <span class="author">Andronov, E.</span> ; <span class="author">...</span> <span class="text-muted pubdata"> - European Physical Journal.

They are derived from data collected by the NA61/SHINE fixed target experiment, by means of invariant mass spectra fits in the $$\phi \to K^+K^-$$ decay channel. They include the first ever measured double differential spectra of $$\phi$$ mesons as a function of rapidity $$y$$ and transverse momentum $$p_T$$ for proton beam momenta of 80 GeV/c and 158 GeV/c, as well as single differential spectra of $$y$$ or $$p_T$$ for beam momentum of 40 GeV/c. The corresponding total $$\phi$$ yields per inelastic p+p event are obtained. These results are compared with existing data on $$\phi$$ meson production in p+p collisions. The comparison shows consistency but superior accuracy of the present measurements. The emission of $$\phi$$ mesons in p+p reactions is confronted with that occurring in Pb+Pb collisions, and the experimental results are compared with model predictions. It appears that none of the considered models can properly describe all the experimental observables.</span><a href='#' onclick='$(this).hide().prev().hide().prev().show();return false;' style='margin-left:10px;display:none;'>« less</a></div><div class="metadata-links small clearfix text-muted" style="margin-top:15px;"> <span class="fa fa-book text-muted" aria-hidden="true"></span> Cited by 6<div class="pure-menu pure-menu-horizontal pull-right" style="width:unset;"> <ul class="pure-menu-list"> <li class="pure-menu-item"><span class="item-info-ftlink"><a class="misc doi-link " href="https://doi.org/10.1140/epjc/s10052-020-7675-6" target="_blank" rel="noopener" title="Link to document DOI" data-ostiid="1561544" data-product-type="Journal Article" data-product-subtype="AM" >https://doi.org/10.1140/epjc/s10052-020-7675-6</a></span></li> <li class="pure-menu-item"><span class="item-info-ftlink"><a class="misc fulltext-link " href="/pages/servlets/purl/1561544" title="Link to document media" target="_blank" rel="noopener" data-ostiid="1561544" data-product-type="Journal Article" data-product-subtype="AM" >Full Text Available</a></span></li> </ul> </div> </div> </div> <div class="clearfix"></div> </div> </li> </ul> </aside> </div> </section> <section id="biblio-related-works" class="tab-content tab-content-sec" data-tab="related"> <div class="padding"> <p class="lead text-muted" style="font-size: 18px;
