Possibility of the experimental study on semi-leptonic and non-leptonic $D^*_{(s)}$ weak decays [PDF]

Just like other heavy flavor mesons, the weak decays of $D^*_{(s)}$ mesons can also provide a platform to check the Standard Model (SM), explore new physics (NP) and understand the mechanisms of weak interactions.

Constraining anomalous Wtb and related SMEFT couplings using low-energy and electroweak precision observables

Journal of High Energy Physics
We investigate constraints on couplings of Standard Model effective field theory (SMEFT) operators contributing to Wtb effective vertex at tree level. We study the one-loop level impact of these couplings on the low-energy flavour changing charged and ...

TeV-scale scalar leptoquarks motivated by B anomalies improve Yukawa unification in SO(10) GUT

Journal of High Energy Physics
It is common practice to explain deviations between data and Standard-Model (SM) predictions by postulating new particles at the TeV scale ad-hoc. This approach becomes much more convincing, if one successfully embeds the postulated particles into a UV ...

Reconstructing Bottom mesons using displaced vertices from semi-leptonic decays [PDF]

, 2007
Precise determination of heavy flavor production cross-sections at LHC energies will be of primary importance. The produced heavy quarks are expected to be sensitive probes of parton energy loss in the medium formed in heavy-ion collisions.

Systematic analysis of $$D_{(s)}$$ D ( s ) meson semi-leptonic decays in the covariant light-front quark model

European Physical Journal C: Particles and Fields
The weak decays of the $$D_{(s)}$$ D ( s ) meson provide a pivotal platform to advance our understanding of the Standard Model (SM) and to explore New Physics (NP). In recent years, experiments have collected a significant amount of data on the $$D_{(s)}$
