The quark fragmentation fractions at LHCb and meson decays with heavy quark spectators

We study the current estimates of to extract the fragmentation fraction at the LHCb. A rather robust estimate of based on factorization…
Toward a search for axion-like particles at the LNLS
L. Angel, P. Arias, C. O. Dib +8
Axion-Like Particles (ALPs) appear in several dark sector studies. They have gained increasing attention from the theoretical and experimental community. In this work, we propose t…
