Ratio $R\left(D_s\right)$ for $B_s\to D_s\ell {\nu }_{\ell }$ by using the QCD light-cone sum rules within the framework of heavy quark effective field theory

Physical Review, 2022
In this paper, we study the Bs→Ds transition form factors by using the light-cone sum rules within the framework of heavy quark effective field theory. We adopt a chiral current correlation function to do the calculation, the resultant transition form factors f+Bs→Ds(q2) and f0Bs→Ds(q2) are dominated by the contribution of Ds-meson leading-twist ...

Effective Field Theories of QCD for Heavy Quarkonia at Finite Temperature [PDF]

, 2011
Quarkonia represent one of the most important probes in the experimental investigation, through heavy-ion collisions, of the quark-gluon plasma. Such bound states were hypothesized to dissociate in this plasma due to the screening of the colour charges and experimental data (SPS, RHIC and LHC) indeed show a suppression pattern. In this thesis we extend

Predicting isovector charmonium-like states from X(3872) properties

Journal of High Energy Physics
Using chiral effective field theory, we predict that there must be isovector charmonium-like D D ¯ ∗ $$ D{\overline{D}}^{\ast } $$ hadronic molecules with J PC = 1++ denoted as W c1.

On determining α s (m Z ) from dijets in e + e − thrust

Journal of High Energy Physics
We update a previous N3LL′+ O α s 3 $$ \mathcal{O}\left({\alpha}_s^3\right) $$ determination of the strong coupling from a global fit to thrust data by including newly available perturbative ingredients, upgrading the renormalization scales to include a ...

Superselection rules, quantum error correction, and quantum chromodynamics

Journal of High Energy Physics
We investigate the relationship between superselection rules and quantum error correcting codes. We demonstrate that the existence of a superselection rule implies the Knill-Laflamme condition in quantum error correction.

Renormalización de una Teoría Efectiva

Momento, 2008
The effective field theories are the best tool to describe that behavior at low energy of a theory known, for example the Quantum Chromodynamics (QCD), but the greater difficulty of these theories is its renormalization. It is necessary doing it order by
