On the possibility of observation of $a_0$-$f_0$ mixing in the $pn o da_0$ reaction | | A. E. Kudryavtsev

22 Feb 2001 | | Journal: | JETP Lett. 72 (2000) 410-414; Pisma Zh.Eksp.Teor.Fiz. 72 (2000) 589-594 | | Subject: | nucl-th | | Abstract: | It is shown that, if isospin is not conserved in $a^0_0$- and $f_0$-meson mixing, forward-backward asymmetry arises in the reaction $pn o da^0_0$. This effect increases near the reaction threshold. The asymmetry is estimated within the framework of a model in which the $a^0_0$-$f_0$ mixing is due to the virtual $pi^0leftrightarroweta$ transition and the difference in masses of the charged and neutral kaons in decay channels. The angular asymmetry near the threshold of the $pn o da^0_0$ reaction was found to be large, of the order of $8div 15$ %. | | Source: | arXiv, nucl-th/0102053 | | Services: | Forum | Review | PDF | Favorites | |
