1. Sensitivity bounds on heavy neutrino mixing |UμN|2 and |UτN|2 from LHCb upgrade / Cvetič, Gorazd ; Kim, C. S.
Decays of heavy pseudoscalar mesons B, Bc, Bs, and Ds at the LHCb upgrade are considered, which produce either two equal sign muons or taus. [...]

2. Renormalon-motivated evaluation of QCD observables / Cvetič, Gorazd
A method of evaluation of spacelike QCD observables D(Q2) is developed, motivated by the renormalon structure of these quantities. [...]

3. Bjorken polarized sum rule and infrared-safe QCD couplings / Ayala, César ; Cvetič, Gorazd ; Kotikov, Anatoly V. ; Shaikhatdenov, Binur G.
Experimental data obtained for the polarized Bjorken sum rule (BSR) Γ1p-n(Q2) are fitted by using predictions derived within a truncated operator product expansion (OPE) approach to QCD. [...]

4. Anomalies in (semi)-leptonic B decays B±→τ±ν, B±→Dτ±ν and B±→D*τ±ν, and possible resolution with sterile neutrinoG.C. acknowledges the support by FONDECYT (Chile) (1130599), The work of C.S.K. was supported in part by the NRF grant funded by the Korean government of the MEST (2016R1D1A1A02936965) / Cvetič, Gorazd ; Halzen, Francis ; Kim, C. S. ; Oh, Sechul
The universality of the weak interactions can be tested in semileptonic b→c transitions, and in particular in the ratios R(D(*)) ≡ Γ(B→D(*)τν)/Γ(B→D(*)lν) (where l=μ or e). [...]

5. The bottom quark mass from the ϒ 1 S $$ \boldsymbol{\Upsilon} (1S) $$ system at NNNLO / César Ayala ; Gorazd Cvetič ; Antonio Pineda
We obtain an improved determination of the normalization constant of the first infrared renormalon of the pole mass (and the singlet static potential). [...]
