This thesis presents a comprehensive study of the single top quark production in association with a WZ boson pair (tWZ), culminating in the first observation of this process. Measurements of rare processes are crucial to improve our understanding of the Standard Model (SM) and improve the sensitivity to loop-induced new physics. [...]

The title compound, [CoII(C3H4N2)6]3(C9H3O6)2 (1), was synthesized from cobalt chloride(II), benzene-1,3,5-tricarboxylic acid (H3btc) and imidazole (Im) in an ethanol/DMF mixture via slow evaporation at room temperature. This compound consists of three hexakis(imidazole)cobalt(II) cations and two trimesate anions. [...]

Experiments were conducted to study the structure and mechanical behavior of high-entropy alloys (HEAs) in the Co-Cr-Fe-Mo-Ni-W compositional library. This investigation was performed on a 3 μm thick combinatorial thin film deposited on a single crystal silicon (c-Si) substrate by magnetron sputtering technique. [...]

High solidification rates and in situ heat treatments are commonly found in additive manufacturing (AM) ofsteels, resulting in a complex and far-from-equilibrium microstructure. Therefore, standard post-processing heattreatments commonly applied to wrought steels can favor the occurrence of different phenomena and can changethe phase transformation sequence, due to the unique microstructure obtained by powder bed fusion – laserbeam (PBF-LB). [...]

The fundamental nature of Dark Matter is a central theme of the Snowmass 2021 process, extending across all frontiers. In the last decade, advances in detector technology, analysis techniques and theoretical modeling have enabled a new generation of experiments and searches while broadening the types of candidates we can pursue. [...]

We observe the radiative decay $D^{*}_{s0}(2317)^{+} \to D_{s}^{*+} γ$ for the first time, with a significance exceeding $10$ standard deviations. The signal is found in the continuum $e^+ e^- \to c\bar{c}$ process with the combined data samples of 980.4~$\rm fb^{-1}$ and 427.9~$\rm fb^{-1}$ collected by the Belle and Belle~II detectors operating at the KEKB and SuperKEKB asymmetric-energy $e^+e^-$ colliders, respectively.
