The $\\mathrm D_{s, 1}^{+}$ and $\\mathrm D_{s, 2}^{*, +}$ mesons were measured at midrapidity ($|y|<0.5$) in minimum-bias and high-multiplicity pp collisions in the transverse-momentum interval $2<p_{\\mathrm T}<24$ GeV$/c$. Their production yields relative to the $D_{s}^{+}$ ground-state yield were found to be compatible between minimum-bias and high-multiplicity collisions, as well as with previous measurements in \\ep and \\ee collisions. The measured $\\mathrm D_{s, 1}^{+}/D_{s}^{+}$ and $\\mathrm D_{s, 2}^{*, +}/D_{s}^{+}$ yield ratios are described by statistical hadronization models and can be used to tune the parameters governing the production of excited charm-strange hadrons in Monte Carlo generators, such as PYTHIA 8.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.158279.v1/t1","@type":"Dataset","description":"$\\mathrm{D_{s1}}^{+}$ x BR($\\mathrm{D_{s1}}^{+} \\rightarrow \\mathrm D^{*+}$ $\\mathrm K^{0}_{S})$ / $\\mathrm{D_{s}^{+}}$ ratio at midrapidity ($|y|<0.5$) in pp collisions at $\\sqrt{s}$ =...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.158279.v1/t2","@type":"Dataset","description":"$\\mathrm{D_{s2}}^{*+}$ x BR($\\mathrm{D_{s2}}^{*+} \\rightarrow \\mathrm D^{+}$ $\\mathrm K^{0}_{S})$ / $\\mathrm{D_{s}^{+}}$ ratio at midrapidity ($|y|<0.5$) in pp collisions at $\\sqrt{s}$ =...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.158279.v1/t3","@type":"Dataset","description":"$\\mathrm{D}_{s1}^{+}$ / $\\mathrm{D}_{s}^{+}$ ratio at midrapidity ($|y|<0.5$) in pp collisions at $\\sqrt{s}$ = 13 TeV BR = (22 $\\pm$ 2)%,...","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.158279.v1/t4","@type":"Dataset","description":"$\\mathrm{D}_{s2}^*{+}$ / $\\mathrm{D}_{s}^{+}$ ratio at midrapidity ($|y|<0.5$) in pp collisions at $\\sqrt{s}$ = 13 TeV BR = 23.35%, branching ratio...","name":"Table 4"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins2829721?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/158279"}],"inLanguage":"en","name":"First measurement of $\\mathrm{D_{s1}}(1^{+})(2536)^+$ and $\\mathrm{D_{s2}^{*}(2^{+})(2573)^+}$ production in proton--proton collisions at $\\sqrt{s} = 13$ TeV at the LHC","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins2829721?version=1","version":1}
