Type: Oral presentation Session: Higgs and photons, electroweak and new physics
Track: DVCS and prompt photons
In this talk we present the diphoton production at NNLO in pQCD. We show the comparison of the NNLO QCD prediction with recent measurements from the LHC. Also we show a study about the isolation prescription and we present the first results on transverse momentum resummation at NNLL+NLO accuracy.

In my talk I will describe role of photons in testing scalar sector of the SM and its extensions. In particular constraints on the Inert Doublet Model will be presented in the light of the recent LHC results on gamma gamma decay of the 125 GeV Higgs. They lead to strong limits on Dark Matter mass and its coupling to the Higgs particle.

ATLAS is one of the general purpose experiments at the Large Hadron Collider (LHC), beginning its data taking in 2009. The Run 1 data taking of ATLAS ran from 2009 until the beginning of 2013, collecting ~25 fb-1 of p-p collision data. After LHC's Long Shutdown 1, ATLAS is restarting its Run 2 data taking operations in just these weeks. In this talk I will give an overview of the most recent re ... More

A measurement of the Higgs boson property with photon final states in proton-proton collisions with the ATLAS detector at the LHC is presented. The results are based on the data samples corresponds to integrated luminosities of 4.7 fb$^{-1}$ at $\sqrt{s}=7$ TeV in 2011 and 20.3 fb$^{-1}$ at $\sqrt{s}=8$ TeV in 2012. From a narrow resonance in diphoton mass spectrum, the mass of the Higgs boson i ... More

Observation of the diphoton decay mode of the recently discovered Higgs boson and measurement of some of its properties are presented. The analysis uses the entire dataset collected by the CMS experiment in proton-proton collisions during the LHC running periods in years 2011 and 2012. The data samples correspond to integrated luminosities of 5.1 $fb^{-1}$ at centre-of-mass energy 7 TeV and 19.7 $...

Measurements of these parameters allow for the exclusion or discovery of contributions beyond the Standard Model. Experimentally, the electroweak gauge couplings are accessible via di-boson production, vector boson production through vector boson fusion, vector boson scattering, and tri ... More Presented by Dr. Ulrike SCHNOOR on 15/6/2015 at 7:30 Session: Higgs and photons, electroweak and new physics Track: Higgs and photons, electroweak and new physics The talk covers CMS results for the limits on anomalous triple and quartic gauge couplings based on data collected with LHC center-of-mass collision energy of sqrt(s)=7 TeV and sqrt(s)=8 TeV with corresponding integrated luminosities of 5 fb^-1 and 19.5 fb^-1 respectively. The limits are derived from the analysis of Vgamma, WV, WVgamma production. All results are consistent with the Standard Model ... More Presented by Mrs. Ekaterina AVDEEVA on 15/6/2015 at 7:55 Session: Higgs and photons, electroweak and new physics Track: Higgs and photons, electroweak and new physics In the last years the Large Hadron Collider (LHC) at CERN has collected a large amount of data considering$pp$,$pPb$and$PbPb$collisions, which is allowing to probe the Standard Model in a new kinematical range. In this talk I will show that the LHC can also be considered as a photon collider, which allows to study several aspects of the hadronic physics by the analysis of photon induced inter ... More Presented by Prof. Victor Paulo GONCALVES on 15/6/2015 at 10:15 Session: Higgs and photons, electroweak and new physics Track: Higgs and photons, electroweak and new physics Isolated photons are a rich probe to explore various physics subjects at LHC. After presenting the strategy to identify the photons and measure the background, the various results of measurements based on photons are reviewed, using collisions based either on protons or lead ions. Presented by Dr. Marc ESCALIER on 15/6/2015 at 8:20 Session: Higgs and photons, electroweak and new physics Track: Higgs and photons, electroweak and new physics A new force beyond the Standard Model (SM) is postulated by several SM extensions and its search is well motivated by many puzzling astrophysical effects recently observed in cosmic ray spectra. The mediator of this “dark force” should be a new neutral light vector gauge boson, known as$U\$ boson, weakly coupled to ordinary particles and associated to an abelian gauge symmetry. Moreover, ...

Within 2HDM deviations of the two-photon Higgs width and the value of triple Higgs coupling from their values in the SM are connected to each other. If SM-like scenario for observed Higgs boson is realized, mentioned deviations can be visible either simultaneously or inaccessible for observation at the LHC. Photon Collider can help in the checking up this connection
