A precise O(10 MeV) measurement of the W boson mass is a stringent test of the standard model. The talk will discuss the experimental and theoretical challenges that need to be faced in order to achieve this level of precision. In addition, the status of various experimental studies, calibrations and state-of-the-art simulations related with this measurement will be presented.

LHC measurements of multi-boson production processes involving combination of up to three W, Z and isolated photons are summarized. The cross sections are measured inclusively and differentially as a function of different kinematic quantities. First measurements of di-boson cross sections at center of mass energy 13TeV are presented. Production processes sensitive to vector-boson fusion and...

We report the LHC measurements of single W and Z boson production at different centre-of-mass energies. Together, the ATLAS, CMS and LHCb detectors provide precision coverage over an absolute rapidity range from 0 to 4.5, enabling precision studies of Standard Model physics across different kinematic regions. We report both differential cross-sections and ratios of W boson and Z boson...

We report on the extraction of sin2θ_eff(MZ) and an indirect measurement of the mass of the W boson from the forward-backward asymmetry of dilepton events in the Z boson mass region at the Tevatron. The data samplesof e+e− and μ+μ− events collected by the CDF detector correspond to the full 9.4 fb−1 run II sample and yield an effective electroweak mixing angle sin2θ_eff(MZ)=0.23222±0.00046....

An overview over recent measurements of top quark properties from the CDF and D0 experiments at the Tevatron proton-antiproton collider is given. We focus on results that are complementary to measurements at the LHC. The results are presented in a systematic way analzsing the top quark pair production mechanism. The presented results involve a new ttbar cross section measurement, a top quark...

In 2015 LHC started operation at a beam energy of 6.5 TeV. After two month beam commissioning period, first collisions were delivered in June 2015. To reach nominal performance with a bunch spacing of 25 ns, the first main hurdle was the conditioning of the vacuum chamber in under to suppress the phenomenon of electron clouds. The conditioning lasted for the rest of 2015 run, the LHC was...

Twenty years past its discovery, the top quark continues attracting great interest as we continue to unveil its properties. An overview of measurements performed by the ATLAS and CMS experiments at the CERN LHC, in the domain of top physics will be presented. The latest measurements of top quark production rates via strong and electroweak processes are reported and compared to different...

The top quark, heaviest known fundamental particle, is the only quark that decays before hadronization. This gives us a unique view on bare quarks properties. Probing top quark couplings with the other fundamental particles open a window to physics beyond the Standard Model. Measuring its properties is therefore of utmost importance. This talk will focus on recent top quark measurements by the...

The interaction strength of the Higgs boson to the building blocks of matter, the electron and up and down quarks, are essentially unknown. Probing these coupling is an important test of the SM which could lead not only to the establishment of new physics but also to an alternative understanding of the flavor puzzle. We propose a novel approach based on isotope shift measurements in atomic...
