Observation of b → dγ decays and determination of |V<sub>td</sub>/V<sub>ts</sub>|
… dγ is a sensitive probe to the Standard Model of elementary particle physics. Using a sample of 386 × 10⁶ B meson pairs accumulated by the Belle detector at the KEKB e⁺e⁻ collider, we measure the branching fractions for the exclusive modes B⁻ → ρ⁻γ, B̅⁰ → ρ⁰γ and B̅⁰ → ωγ as follows: B(B⁻ → ρ⁻γ) = …

Initial systematic investigations of the weakly coupled free fermionic heterotic string landscape statistics.
A C++ framework was constructed with the explicit purpose of systematically generating string models using the Weakly Coupled Free Fermionic Heterotic String (WCFFHS) method. The software, optimized for speed, generality, and ease of use, has been used to conduct preliminary systematic …

Measurement of J/ψ meson production in association with a W [superscript ±] boson in pp data at 13 TeV collected by the ATLAS experiment
This dissertation presents a measurement of the production cross-section of J/ψ mesons in association with a W [superscript ±] boson in √s = 13 TeV pp collisions by the ATLAS experiment, using 139 fb⁻¹ of integrated luminosity produced by the Large Hadron Collider at CERN. Events are selected with …
