Results in Precision Multiboson+Jet Phenomenology
Francisco Campanario, Christoph Englert, Michael Rauch +2
We review recent results in precision multiboson+jet phenomenology at the LHC. We discuss strategies how to compute these processes at NLO QCD and examine the impact of the perturb…
Iron and alpha-element Production in the First One Billion Years after the Big Bang
George D. Becker, Wallace L. W. Sargent, Michael Rauch +1
We present measurements of carbon, oxygen, silicon, and iron in quasar absorption systems existing when the universe was roughly one billion years old. We measure column densities…
Measuring the Higgs boson couplings
Michael Rauch
Once a Higgs boson has been discovered, it is also important to know what are its properties, in particular its couplings to the other particles. At the LHC, there will be many obs…
Zγγproduction with leptonic decays and triple photon production at NLO QCD
G. Bozzi, F. Campanario, M. Rauch +1
We present a calculation of the O(alpha_s) QCD corrections to the production of a Z boson in association with two photons and to triple photon production at hadron colliders. All f…
Precise predictions for W γγ+jet production at hadron colliders
Francisco Campanario, Christoph Englert, Michael Rauch +1
In this letter we report on a calculation of W gamma gamma + jet production at next-to-leading order QCD. We include the leptonic decays of the W and take into account all off-shel…
Filamentary Infall of Cold Gas and Escape of Lyman Alpha and Hydrogen Ionizing Radiation from an Interacting High-Redshift Galaxy
Michael Rauch, George D. Becker, Martin G. Haehnelt +3
We present observations of a peculiar Lyman alpha-emitting galaxy at redshift 3.344, discovered in a deep, blind spectroscopic survey for faint Lyman alpha emitters with the Magell…
Wγγproduction with leptonic decays at NLO QCD
G. Bozzi, F. Campanario, M. Rauch +1
The computation of the NLO-QCD corrections to the cross sections for W γγproduction in hadronic collisions is presented. We consider the case of real photons in the final state, bu…
High-Redshift Metals. II. Probing Reionization Galaxies with Low-Ionization Absorption Lines at Redshift Six
George D. Becker, Wallace L. W. Sargent, Michael Rauch +1
We present a survey for low-ionization metal absorption line systems towards 17 QSOs at redshifts z_em=5.8-6.4. Nine of our objects were observed at high resolution with either Kec…
