Study of the decay $B^0 \to \chi_{c1} K^+ \pi^-$ and search of exotic resonances at LHCb
In 2008 the Belle Collaboration reported the observation of two charged resonance-like structures in the ${\chi_c}_1 \pi^-$ mass spectrum produced in the decay $B^0 \to {\chi_c}_1 K^+ \pi^-$. These were labelled as $Z_1(4050)^-$ and $Z_2(4250)^-$. Alternatively, a single wider resonance hypothesis w...
