Are you an EPFL student looking for a semester project?
Work with us on data science and visualisation projects, and deploy your project as an app on top of Graph Search.
The first dedicated search for the eta(c2)(1D) is carried out using the decays B+-> eta(c2)(1D)K+, B-0 -> eta(c2)(1D)KS0 with eta(c2)(1D) -> h(c)gamma. No significant signal is found. For the eta(c2)(1D) mass range between 3795 and 3845 MeV/c(2), the branching-fraction upper limits are determined to be & x212c;(B+-> eta(c2)(1D)K+) x & x212c;(eta(c2)(1D) -> h(c)gamma) < 3.7 x 10(-5), & x212c;(B-0 -> eta(c2)(1D)K-0) x & x212c;(eta(c2)(1D) -> h(c)gamma) < 3.5 x 10(-5), & x212c;(B-0 -> eta(c2)(1D)pi K--(+)) x & x212c;(eta(c2)(1D) -> h(c)gamma) < 1.0 x 10(-4), and & x212c;(B+-> eta(c2)(1D)pi(+)KS0) x & x212c;(eta(c2)(1D) -> h(c)gamma) < 1.1 x 10(-4) at 90% C.L. The analysis is based on the 711 fb(-1) data sample collected on the & x3d2;(4S) resonance by the Belle detector, which operated at the KEKB asymmetric-energy e(+)e(-) collider.
