A catalog of new Blazar candidates with Open Universe by High School students

Blazars are active galactic nuclei whose ultra-relativistic jets are coaligned with the observer direction. They emit throughout the whole e.m. spectrum, from radio waves to VHE gamma rays. Not all blazars are discovered. In this work, we propose a catalog of 54 new candidates based on the association of HE gamma ray emission and radio, X-ray an optical signatures. The relevance of this work is also that it was performed by four high school students from the Liceo Scientifico Statale Ugo Morin in Venice, Italy using the open-source platform Open Universe, in collaboration with the University of Padova. The framework of the activity is the Italian MIUR PCTO programme. The success of this citizen-science experience and results are hereafter reported and discussed.Comment: Proceedings of the 12th Cosmic Ray International Symposium (CRIS 2022), 12-16 September 2022, Naples (Italy).

Theoretical update of the semileptonic branching ratio of B mesons

We reconsider the prediction of the semileptonic branching ratio of B mesons, using a recent calculation of the radiative corrections with account for finite quark masses in nonleptonic decays and taking into account 1/m_b"2 corrections. For the semileptonic branching ratio we obtain B_S_L=(11.8#+-#1.6)% using pole quark masses and B_S_L=(11.0#+-#1.9)% using running anti M anti S quark masses. The uncertainty is dominated by unknown higher oder perturbative corrections. We conclude that the present accuracy of the theoretical analysis does not allow to state a significant disagreement with the experimental results. However, our re-analysis of the decay b#->#ccs yields an increase of (35#+-#11)% due to next-to-leading order corrections including mass dependent terms, which further emphasizes the problem of the average charm quark content of the final state in B decays.
