Matter effects on $η$ and $η^{'}$ mesons

Vivek Kumar Tiwari, Anirban Kundu

We show how the nuclear medium affects the masses of the $η$ and $η^{'}$ mesons. The change should be easily detectable for dense matter and/or strong $η (η^{'}) N N ˉ$ coupling. We also…

Semileptonic charm decay as a test for the spectator model in the $B_{c}$ -meson

Debajyoti Choudhury, Anirban Kundu, Biswarup Mukhopadhyaya

The $b$ and the $c$ quark compete with each other in decays of the $B_{c}$ -meson. We emphasize the need of obtaining reliable signals of $c \to s$ in order to assess the merits of th…
