<jats:title>Abstract</jats:title> <jats:p>Using gauge/gravity duality, we investigate the string breaking and dissolution of two heavy quarks coupled to a light quark at finite temperature. It is found that three configurations of <jats:italic>QQq</jats:italic>exist with the increase in separation distance for heavy quarks in the confined phase. Furthermore, string breaking occurs at the distance <jats:inline-formula> <jats:tex-math><?CDATA $ L_{QQq} = 1.27\; {\rm{fm}} $?></jats:tex-math> <jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="cpc_46_7_073102_M1.jpg" xlink:type="simple" /> </jats:inline-formula> ( <jats:inline-formula> <jats:tex-math><?CDATA $ T = 0.1\; {\rm{GeV}} $?></jats:tex-math> <jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="cpc_46_7_073102_M2.jpg" xlink:type="simple" /> </jats:inline-formula>) for the decay mode <jats:inline-formula> <jats:tex-math><?CDATA $ {Q Q q} \rightarrow {Q q q+Q \bar{q}} $?></jats:tex-math> <jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="cpc_46_7_073102_M3.jpg" xlink:type="simple" /> </jats:inline-formula>. In the deconfined phase, <jats:italic>QQq</jats:italic> melts at a certain distance and then becomes free quarks.

<jats:title>Abstract</jats:title> <jats:p>Based on the recent precise measurements by the BESIII collaboration for electron–positron annihilation into a neutron and antineutron pair, the effective form factors of the neutron were determined in the time-like region, and it was found that the effective form factors of the neutron are smaller than those of the proton. The effective form factors of the neutron show a periodic behaviour, similar to those of the proton. Here, a comparative analysis for Λ, <jats:inline-formula> <jats:tex-math><?CDATA $ \Sigma^0 $?></jats:tex-math> <jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="cpc_46_7_073104_M1.jpg" xlink:type="simple" /> </jats:inline-formula> and <jats:inline-formula> <jats:tex-math><?CDATA $ \Xi^0 $?></jats:tex-math> <jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="cpc_46_7_073104_M2.jpg" xlink:type="simple" /> </jats:inline-formula> hyperons is performed.

After determining strong interaction phases and obtaining factorizable contributions from spectator-quark diagrams for <jats:italic>N</jats:italic> <jats:sub> <jats:italic>c</jats:italic> </jats:sub>=3, we determine nonfactorizable isospin amplitudes from the experimental data for these modes.

To demonstrate that these systematics are not coincidental, we also plot our results w. r. t. this ratio. </jats:p>

The obtained results are also compared with the results obtained using the Standard Model. </jats:p>

A general description of the decay is developed using Euler angles, and the polarization parameters are derived.

The experimental measurement of these asymmetry parameters is suggested. </jats:p>
