The detailed study of the Higgs boson is one of the main tasks of contemporary particle physics. Gluon fusion, the main production channel of Higgs bosons at the LHC, has been successfully modelled in QCD up to $\text{N}^3\text{LO}$. To fully exploit this unprecedent theoretical effort, sub-leading contributions, such as electroweak corrections, must be investigated. I will present the...
Since Feynman integrals in QFT evaluate to special functions and numbers,
it is essential to profit from this knowledge to extract in a simple way
preliminary information of multi-loop scattering amplitudes.
To this end, one can focus on their maximal transcendental weight contribution.
In this talk, I report on a method that uses insights into
the singularity structure of space-time...
Up to now, NNLO QCD calculations of photon production cross sections applied an idealised photon isolation procedure, which differs from the isolation used in experiments. We present first numerical results for NNLO QCD predictions of isolated photon cross sections at the LHC with a realistic cone-based isolation. Photon fragmentation processes are included for the first time at NNLO, by...
Single top quark is mainly produced through the t-channel W boson exchange q + b -> q + t at LHC. This process probes Wtb vertex directly and can be used to measure the CKM matrix element Vtb or constrain the bottom quark PDF. The two-loop non-factorisable contribution is the last missing piece of the NNLO correction. In this talk, I will first talk about its motivation, then I will discuss...
Jet mass measurements for processes involving boosted top quark pair production will be possible at the HL-LHC and may become an important tool for high-precision
measurements of the top quark mass in a well-defined renormalization scheme. Apart from including QCD corrections and resummations, for which well-developed frameworks exist,
eventually also electroweak and finite-lifetime effects...
In my talk I would like to summarize our recent work we did
in the computation of the associated W vector boson production
with a massive charm quark at the Next-to-Leading Order accuracy
in QCD at the hadron level. This process plays an important role
in the determination of PDFs for sea quarks hence provides an
important, indirect input to several precision measurements at the
LHC.
