Are there narrow flavorexotic tetraquarks in large${N}_{c}$ QCD?
/ Lucha, Wolfgang ; Melikhov, Dmitri ; Sazdjian, Hagop
A salient feature shared by all tetraquark candidates observed in experiment is the absence of flavorexotic states of the type $\overline{a}b\overline{c}d$, with four different quark flavors. [...]

Rare FCNC radiative leptonic ${B}_{s,d}\to \gamma {l}^{+}{l}^{}$ decays in the standard model
/ Kozachuk, Anastasiia ; Melikhov, Dmitri ; Nikitin, Nikolai
We revisit rare radiative leptonic decays ${B}_{s,d}\to \gamma {e}^{+}{e}^{}$ and ${B}_{s,d}\to \gamma {\mu}^{+}{\mu}^{}$ in the standard model and provide the updated estimates for various differential distributions (the branching ratios, the forwardbackward asymmetry, and ${R}_{\mu /e}$, the ratio of the differential distribution for muons over electrons in the final state).

Tetraquark and twomeson states at large Nc
/ Lucha, Wolfgang ; Melikhov, Dmitri ; Sazdjian, Hagop
Considering fourpoint correlation functions of colorsinglet quark bilinears, we investigate, in the large Nc limit of QCD, the subleading diagrams that involve, in the s channel of meson–meson scattering amplitudes, twoquark–twoantiquark intermediate states. [...]

Isospin breaking in the decay constants of heavy mesons from QCD sum rules
/ Lucha, Wolfgang ; Melikhov, Dmitri ; Simula, Silvano
We present a study of the strong isospinbreaking (IB) effect, due in QCD to the difference between u  and d quark masses, in the leptonic decay constants of charmed and beauty pseudoscalar and vector mesons using the method of QCD sum rules. [...]

More lepton flavor violating observables for LHCb's run 2
/ Guadagnoli, Diego ; Melikhov, Dmitri ; Reboud, Méril
The RK measurement by LHCb suggests nonstandard lepton nonuniversality (LNU) to occur in b→sℓ+ℓ− transitions, with effects in muons rather than electrons. [...]
