QCD-factorization amplitudes from flavour symmetries: beyond the symmetric case
Wen-Sheng Fang, Tobias Huber, Xin-Qiang Li +2
Using experimental information on branching ratios as well as direct and mixing-induced CP asymmetries, we perform a data-driven analysis of charmless non-leptonic decay…
Optimised Inference of Quantum Phenomena in High-Energy Collider Experiments
Hai-Chau Nguyen, Gilberto Tetlalmatzi-Xolocotzi, Carmen Diez Pardos +2
Entanglement, a fundamental phenomenon of quantum theory, has recently been observed in processes in high-energy physics. This opens new avenues for probing quantum effects in rela…
Enhancing to an Observable Level in the Two-Higgs-Doublet Model
Matthew Black, Alexis D. Plascencia, Gilberto Tetlalmatzi-Xolocotzi
As a result of the helicity suppression effect, within the Standard Model the rare decay channel has a decay probability which is five orders of magnitude below c…
Model-independent bounds on new physics effects in non-leptonic tree-level decays of B-mesons
Alexander Lenz, Gilberto Tetlalmatzi-Xolocotzi
We present a considerably improved analysis of model-independent bounds on new physics effects in non-leptonic tree-level decays of B-mesons. Our main finding is that contributions…
Rare Leptonic B decays
Gilberto Tetlalmatzi-Xolocotzi
The transitions (for ), although extremely suppressed within the SM, are exceptionally clean channels particularly sensitive to New…
Double-charming Higgs identification using machine-learning assisted jet shapes
Alexander Lenz, Michael Spannowsky, Gilberto Tetlalmatzi-Xolocotzi
We study the possibility of identifying a boosted resonance that decays into a charm pair against different sources of background using QCD event shapes, which are promoted to jet…
On the ultimate precision of meson mixing observables
Thomas Jubb, Matthew Kirk, Alexander Lenz +1
Meson mixing is considered to be an ideal candidate for new physics searches. Current experimental precision has greatly increased over the recent years, excelling in several cases…
New physics in
Gilberto Tetlalmatzi-Xolocotzi
We analyze the possibility of having new physics effects in the decay rate difference, , of neutral mesons. Three different sources of enhancement are considered, CKM u…
New physics effects in tree-level decays
Joachim Brod, Alexander Lenz, Gilberto Tetlalmatzi-Xolocotzi +1
We critically review the assumption that no new physics is acting in tree-level -meson decays and study the consequences for the ultimate precision in the direct determination o…
On new physics in
Christoph Bobeth, Ulrich Haisch, Alexander Lenz +2
Motivated by the recent measurement of the dimuon asymmetry by the DØ collaboration, which could be interpreted as an enhanced decay rate difference in the neutral -meson syst…
