Vector leptoquark resolution of and puzzles
Svjetlana Fajfer, Nejc Košnik
We propose that three recent anomalies in meson decays, , , and , might be explained by a single vector leptoquark weak triplet state. The constraints o…
Prospects of discovering new physics in rare charm decays
Svjetlana Fajfer, Nejc Košnik
The LHCb bounds on the branching ratio of rare decay and the constraints on the branching ratio of in the nonresonant regions enable us to i…
Theoretical perspective on rare and radiative charm decays
Svjetlana Fajfer
Recent experimental bounds on rare charm decays offer a chance to improve our theoretical understanding of physics present in and transitions. Standar…
Chiral loops in the isospin violating decays of D_{s1}(2460) and D*_{s0}(2317)
Svjetlana Fajfer, Anita Prapotnik Brdnik
Positive parity meson states D*_{s0}(2317) and D_{s1}(2460) have masses slightly below the DK threshold. Therefore, both states can strongly decay only into isospin violating decay…
Lepton flavor non-universality in processes
Damir Bečirević, Svjetlana Fajfer, Nejc Košnik
We explore a scenario of New Physics entering the description of decay through couplings to the operators , satisfying $C_9^\prime = -…
Discerning new physics in charm meson leptonic and semileptonic decays
Svjetlana Fajfer, Ivan Nisandzic, Ursa Rojec
Current experimental information on the charm meson decay observables in which the transitions occur is well compatible with the Standard Model predictions. Rece…
