Scattering light by light at 750 GeV at the LHC
Fichet, S. [UNESP]; Von Gersdorff, G. [UNESP]; Royon, C.Made available in DSpace on 2022-04-29T07:35:48Z (GMT). No. of bitstreams: 0 Previous issue date: 2016-04-20; We consider the possibility that the diphoton excess at 750 GeV is caused by a new scalar resonance produced in photon fusion. This scenario is parametrized by only one relevant effective couplings and is thus minimal. We show that this setup can reproduce both the production rate and width of the reson...
Measuring the Diphoton Coupling of a 750 GeV Resonance
Fichet, S. [UNESP]; Von Gersdorff, G.; Royon, C.Made available in DSpace on 2022-04-29T07:39:01Z (GMT). No. of bitstreams: 0 Previous issue date: 2016-06-08; A slight excess has been observed in the first data of photon-photon events at the 13 TeV Large Hadron Collider that might be interpreted as a hint of physics beyond the standard model. We show that a completely model-independent measurement of the photon-photon coupling of a putative 750 GeV resonance ...

Searching for axion-like particles with proton tagging at the LHC
Baldenegro, C.; Fichet, S. [UNESP]; von Gersdorff, G.; Royon, C.Made available in DSpace on 2018-12-11T17:21:03Z (GMT). No. of bitstreams: 0 Previous issue date: 2018-06-01; The existence of an axion-like particle (ALP) would induce anomalous scattering of light by light. This process can be probed at the Large Hadron Collider in central exclusive production of photon pairs in proton-proton collisions by tagging the surviving protons using forward proton detectors. Using a ...
Probing the anomalous γγγZ coupling at the LHC with proton tagging
Baldenegro, C.; Fichet, S. [UNESP]; von Gersdorff, G.; Royon, C.Made available in DSpace on 2018-12-11T17:13:04Z (GMT). No. of bitstreams: 0 Previous issue date: 2017-06-01; The sensitivities to the anomalous quartic gauge boson coupling γγγZ are estimated via γZ production with intact protons in the forward region at the LHC. Proton tagging proves to be a powerful tool to suppress the background, which allows consideration of the hadronic decays of the Z boson in addition ...
