decays is conducted by analysing the

All physical processes can be described, at a fundamental level, through interactions of elementary particles. The Standard Model of particle physics (SM) describes three of the four known fundamental forces and all of the known elementary particles. The a ...

One of the main goals of studying semileptonic decays in flavor physics is to gain a better understanding of hadronic transitions in the nonperturbative region of Quantum Chromodynamics. This involves measuring Cabibbo-Kobayashi-Maskawa matrix elements, un ...

A first determination of the strong-phase difference between D0 and D0¯→K+K-π+π- is performed using e+e-→ψ(3770)→DD¯ data collected by the BESIII detector corresponding to an integrated luminosity of 20.3 fb-1. The measurements are made in four pairs of bi ...

Our motivation in this paper is twofold. First, we study the geometry of a class of exploration sets, called exit sets, which are naturally associated with a 2D vector-valued Gaussian Free Field:

\phi : \mathbb{Z}^2 \rightarrow \mathbb{R}^N

N \ge 1

. W ...

Using (27.12 +/- 0.14) x 10(8) psi(2S) events collected by the BESIII detector operating at BEPCII, we search for the decay eta(c) (2S) -> p (p) over bar via the process psi(2S) -> gamma eta(c)(2S) and only find a signal with a significance of 1.7 sigma. T ...

The first evidence for the decay B^{-}→D^{**0}τ^{-}ν[over ¯]_{τ} is obtained using proton-proton collision data collected by the LHCb experiment, corresponding to an integrated luminosity of 9 fb^{-1}, at centre-of-mass energies of 7, 8, and 13 TeV. Here, ...

A search for heavy, long-lived, charged particles with large ionization energy loss within the silicon tracker of the CMS experiment is presented. A data set of proton-proton collisions at a center of mass energy at s = 13 TeV, collected in 2017 and 2018 a ...

A large variety of new physics models suggest that the rates for lepton flavour violating

-hadron decays may be much higher than predicted in the Standard Model, which leads to a high interest in the search for such decays. This thesis presents the se ...

Six C-even states, denoted as X, with quantum numbers J(PC) = 0(-+), 1(++), or 2(++), are searched for via the e(+)e(-) -> gamma(DsDs*-/+)-D-+/- process using (1667.39 +/- 8.84) pb(-1) of e(+)e(-) collision data collected with the BESIII detector operating ...

The measurement of Z boson production is presented as a method to determine the integrated luminosity of CMS data sets. The analysis uses proton-proton collision data, recorded by the CMS experiment at the CERN LHC in 2017 at a center-of-mass energy of 13 ...

The first search for ultra-rare K+ decays into the pi(+)e(+)e(-) e(+) e(-) final state is reported, using a dataset collected by the NA62 experiment at CERN in 2017-2018. An upper limit of 1.4x10(-8) at 90% CL is obtained for the branching ratio of the K+ ...

Using (10087 +/- 44) x 10(6) J/psi events collected with the BESIII detector, we search for the rare decay J/psi -> gamma D-0 + c.c. for the first time. No significant signal is observed and the upper limit on the branching fraction is determined to be B(J ...

This PhD thesis aims at testing one of the fundamental properties of the Standard Model (SM) of particle physics: the lepton flavour universality (LFU), which states that
