The result of a search for flavor changing neutral currents (FCNC) through single top quark production in association with a photon is presented. The study is based on proton-proton collisions at a center-of-mass energy of 8 TeV using data collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 19.8 inverse femtobarns. The search for t gamma events where t $\\rightarrow$ Wb and W to $\\mu$ $\\nu$ is conducted in final states with a muon, a photon, at least one hadronic jet with at most one being consistent with originating from a bottom quark, and missing transverse momentum. No evidence of single top quark production in association with a photon through a FCNC is observed. Upper limits at the 95% confidence level are set on the tu gamma and tc gamma anomalous couplings and translated into upper limits on the branching fraction of the FCNC top quark decays: B(t $\\rightarrow u \\gamma$) < 1.3$\\times$10$^{-4}$ and B(t $\\rightarrow c \\gamma$) < 1.7$\\times$10$^{-3}$. Upper limits are also set on the cross section of associated t gamma production in a restricted phase-space region. These are the most stringent limits currently available.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.70010.v1/t1","@type":"Dataset","description":"The expected and observed $95\\%$ CL upper limits on the FCNC $tu\\gamma$ and $tc\\gamma$ cross sections times branching fraction, the...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.70010.v1/t2","@type":"Dataset","description":"The expected and observed $95\\%$ CL upper limits on the FCNC $tu\\gamma$ and $tc\\gamma$ cross sections times branching fraction, the...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.70010.v1/t3","@type":"Dataset","description":"Upper limits on the signal cross sections are also determined for a restricted phase-space region in which the detector is...","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.70010.v1/t4","@type":"Dataset","description":"For the tu$\\gamma$ signal channel, the total number of observed selected events in the data (N$_{obs}$), the SM expectations (N$_{SM}$),...","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.70010.v1/t5","@type":"Dataset","description":"For the tc$\\gamma$ signal channel, the total number of observed selected events in the data (N$_{obs}$), the SM expectations (N$_{SM}$),...","name":"Table 5"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1404159?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/70010"}],"inLanguage":"en","name":"Search for anomalous single top quark production in association with a photon in pp collisions at sqrt(s) = 8 TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1404159?version=1","version":1}
