Hi all,

Christian Weiss asked me to forward the seminar announcement below. This 
might be interesting for some of you.


Cheers,
Boris

> *_Abstract_*: The discovery of XYZ exotic states in the hadronic 
> sector, particularly those containing two heavy quarks, remains one of 
> the most intriguing open problems in particle physics. In this talk, I 
> present the Born-Oppenheimer Effective Field Theory (BOEFT), a 
> framework derived from QCD, capable of describing exotic hadrons of 
> any composition. I discuss the general Schrödinger coupled equations 
> governing arbitrary angular momentum of light degrees of freedom, 
> capturing the dynamics of hybrids, tetraquarks, pentaquarks, doubly 
> heavy baryons, and quarkonia at leading order—including nonadiabatic 
> effects. I also explore the predicted multiplet structures, selection 
> rules, and key nonperturbative gauge-invariant correlators—such as 
> static energies, generalized Wilson loops, gluelumps, and adjoint 
> mesons—which serve as essential lattice QCD inputs for 
> BOEFT. Moreover, I show for the first time new results on the behavior 
> of static energies at short distances and mixing with the threshold at 
> long distances based on BOEFT. As an application, I show results for 
> the hybrid spectrum, hybrid decays to quarkonium, results for X(3872) 
> and T_cc (3875), and preliminary results on pentaquark states.
