Photon emissivity of the quark-gluon plasma: A lattice QCD analysis of the transverse channel
2022
We present results for the thermal photon emissivity of the quark-gluon plasma derived from spatially transverse vector correlators computed in lattice QCD at a temperature of 250 MeV. The analysis of the spectral functions, performed at fixed spatial momentum, is based on continuum-extrapolated correlators obtained with two flavours of dynamical Wilson fermions. We compare the next-to-leading order perturbative QCD correlators, as well as the ${\cal N}=4$ supersymmetric Yang-Mills correlators at infinite coupling, to the correlators from lattice QCD and find them to lie within $\sim10\%$ of each other. We then refine the comparison, performing it at the level of filtered spectral functions…

Vertex-level efficiency as a function of the vertex radial position for an RPV SUSY model of squark production with $\tilde{q}\to q[\tilde{\chi}_1^0\to\mu qq]$, where $m(\tilde{q}) = 700$ GeV, $m(\tilde{\chi}_1^0) = 494$ GeV and $c\tau(\tilde{\chi}_1^0)$ = 175 mm. This result is also represented in Figure 3b and Auxiliary Figure 1.

Vertex-level efficiency if no re-tracking is performed, as a function of the vertex radial position for an RPV SUSY model of squark production with $\tilde{q}\to q[\tilde{\chi}_1^0\to\mu qq]$, where $m(\tilde{q}) = 700$ GeV, $m(\tilde{\chi}_1^0) = 494$ GeV and $c\tau(\tilde{\chi}_1^0)$ = 175 mm. The result with re-tracking is tabulated in http://hepdata.cedar.ac.uk/view/ins1362183/d1.

Vertex-level efficiency as a function of the vertex radial position for an RPV SUSY model of squark production with $\tilde{q}\to q[\tilde{\chi}_1^0\to\mu qq]$, where $m(\tilde{q}) = 700$ GeV, $m(\tilde{\chi}_1^0) = 108$ GeV and $c\tau(\tilde{\chi}_1^0)$ = 101 mm.

Upper limits (95% CL) from the DV+$E_T^{miss}$ channel on the production cross-section and the corresponding event-level efficiencies (from Auxiliary Figure 11b) for four RPV SUSY models as a function of the $\tilde{\chi}_1^0$ proper decay distance $c\tau$. The models consider squark pair production, with $\tilde{q}\to q\tilde{\chi}_1^0$ decays and masses in GeV as indicated. For comparison, the production cross-sections for $m(\tilde{q})$ = 700 GeV and 1000 GeV are $124\pm17$ fb and $11.9\pm1.5$ fb, respectively.

Vertex mass distributions in data and one RPV SUSY signal model, for vertices with 3, 4 and $\geq$5 tracks in the DV+muon channel. The entries are the number of DVs in each bin, not normalized according to bin size. The signal model is for squark pair production, with $\tilde{q}\to q[\tilde{\chi}_1^0\to\mu qq]$ decays, $m(\tilde{q})$ = 700 GeV, $m(\tilde{\chi}_1^0)$ = 494 GeV and $c\tau(\tilde{\chi}_1^0)$ = 175 mm.
