Study of Double Parton Scattering Using Four-Jet Scenariosin Proton-Proton Collisions at $\sqrt{s} = 7$ TeV with the CMS Experiment at the LHC
Basel : Springer International Publishing : Springer Theses, 279 ()
This thesis addresses in a very new and elegant way several measurements and the extraction of so-called double parton scattering. The new and elegant way lies in the combination of measurements and a very smart extraction of double parton scattering results, which is easy to apply and overcomes many of the technical difficulties of older methods.

Determination of TMD parton densities from HERA data and application to pp processes
[DESY-THESIS-2018-024]
Hamburg : Verlag Deutsches Elektronen-Synchrotron, DESY-THESIS 138 pp. () [10.3204/PUBDB-2018-02949] = Dissertation, Universit├Ąt Hamburg, 2018  GO
The topic of this thesis is a new approach to solve the DGLAP evolution equation to obtain not only the collinear Parton Distribution Functions (PDFs) but also the Transverse Momentum Dependent (TMD) PDFs (TMDs). The DGLAP equation is solved with the Parton Branching (PB) method, which allows a determination of kinematic variables at every branching and a construction of the TMDs in a large range in longitudinal momentum fraction $x$ and evolution scale $\mu^2$.

Experimental results using the decay of the Higgs to taus and muons
Sixth Annual Conference on Large Hadron Collider Physics, LHCP2018, BolognaBologna, Italy, 4 Jun 2018 - 9 Jun 20182018-06-042018-06-09  GO
A search for new Higgs bosons produced in association with bottom quarks and decaying into a bottom anti-bottom quark pair is performed with the CMS detector. The data collected for this analysis were recorded in proton-proton collisions at a centre-of-mass energy of 13 TeV in 2016, corresponding to an integrated luminosity of 35.7 fb-1. [...]

Properties of the discovered 125 GeV Higgs boson are in good agreement with the predictions of the Standard Model (SM). However, the current precision of these measurements, allows models, such as Supersymmetry, with extended Higgs sectors, in which the discovered Higgs boson is only one of several Higgs bosons. [...]

State-of-the-art theoretical predictions accurate to next-to-leading order QCD interfaced with Pythia8, Herwig, and Sherpa event generators are tested by comparing the unfolded ttbar differential data collected with the CMS detector at 8 and 13 TeV. These predictions are also compared with the underlying event activity distributions in ttbar events using CMS proton-proton data collected at a center of mass energy of 13 TeV. [...]
