Towards a Stringy Description for the $Q\bar Q q\bar q$-Quark System

  title={Towards a Stringy Description for the \$Q\bar Q q\bar q\$-Quark System},
  author={Oleg Yu. Andreev},
For the case of two light flavors we propose the stringy description of the system made of one heavy and one light quark-antiquark pair, with the aim of exploring the two lower-lying Born-Oppenheimer potentials as a function of a separation of the heavy quark-antiquark pair. Our analysis reveals three critical separations related to the processes of string reconnection, breaking and junction annihilation. In particular, for the ground state potential only the process of string reconnection…

Deciphering the XYZ States

I give a brief account of current topics in description of exotic multiquark mesonic resonances with hidden heavy ($c$ or $b$) flavor, the so-called XYZ states, in terms of hadronic molecules and
