dc.description.abstract
After the Higgs boson discovery, LHC turned into the precision machine to explore its properties. In case new resonances will not be found, the only access to New Physics would be via measuring small deviations from the SM predictions. A consistent approach which can be useful in both above cases is a bottom-up Effective Field Theory, with dimension six operators build of Standard Model fields. We present how this approach would work in case of the transverse momentum spectrum of the Higgs particle. In our calculation we augmented the Standard Model with three additional operators: modifications of the top and bottom Yukawa couplings, and a point-like Higgs coupling to gluons. We present resummed transverse-momentum spectra including the effect of these operators at NLL+NLO accuracy and study their impact on the shape of the distribution. We find that such modifications, while affecting the total rate within the current uncertainties, can lead to significant distortions of the spectrum. We also discuss the effect of the chromomagnetic operator on the Higgs production cross section at LO.
