Abstract: (APS)

Inspired by the

T_{c c}^{+}

signal discovered by the LHCb Collaboration, we systematically investigate the doubly heavy tetraquark states with the molecule configuration

[Q_{1} {\bar{q}}_{2}]_{1_{c}} [Q_{3} {\bar{q}}_{4}]_{1_{c}}

(

Q = c

and

b

,

q = u

,

d

, and

s

) in a nonrelativistic quark model. The model involves a color screening confinement potential, meson-exchange interactions, and one-gluon-exchange interactions. The state

T_{c c}^{+}

with

I J^{P} = 0 1^{+}

is a very loosely bound deuteronlike state with a binding energy around 0.34 MeV and a huge size of 4.32 fm. Both the meson exchange force and the coupled channel effect play a pivotal role. Without the meson exchange force, there does not exist the

T_{c c}^{+}

molecular state. In strong contrast, the QCD valence bond forms clearly in the

T_{b b}^{-}

system when we turn off the meson-exchange force, which is very similar to the hydrogen molecule in QED. Moreover, the

T_{b b}^{-}

becomes a heliumlike QCD-atom if we increase the bottom quark mass by a factor of three. Especially, the states

T_{b b}^{-}

with

01^{+}

,

T_{b c}^{0}

with

00^{+}

and

01^{+}

, and the

V

-spin antisymmetric states

T_{b b s}^{-}

with

\frac{1}{2} 1^{+}

,

T_{b c s}^{0}

with

\frac{1}{2} 0^{+}

and

\frac{1}{2} 1^{+}

can form a compact, hydrogen moleculelike or deuteronlike bound state with different binding dynamics. The high-spin states

T_{b c}^{0}

with

02^{+}

and

T_{b c s}^{0}

with

\frac{1}{2} 2^{+}

can decay into

D

-wave

\bar{B} D

and

{\bar{B}}_{s} D

although they are below the thresholds

{\bar{B}}^{*} D^{*}

and

{\bar{B}}_{s}^{*} D^{*}

, respectively. The isospin and

V

-spin symmetric states are unbound. We also calculate their magnetic moments and axial charges.
