Query: X(3872) and its production at hadron colliders   We evaluate the production cross sections of $X(3872)$ at the LHC and
Tevatron at NLO in $\alpha_s$ in NRQCD by assuming that the short-distance
production proceeds dominantly through its $\chi_{c1}'$ component in our
$\chi_{c1}'\mbox{-}D^0\bar{D}^{*0}$ mixing model for $X(3872)$. The outcomes of
the fits to the CMS $p_T$ distribution can well account for the recent ATLAS
data in a much larger range of transverse momenta
($10~\mbox{GeV}<p_T<70~\mbox{GeV}$), and the CDF total cross section data, and
are also consistent with the value of $k=Z_{c\bar c}\cdot Br(X\to
J/\psi\pi^+\pi^-)$ constrained by the $B$-meson decay data. %It can also well
describe the behavior of the CDF $\psi(2S)$ data, which show a strong
%resemblance to that of the X(3872). For LHCb the predicted X(3872) total cross
section is larger than the data by a factor of 2, which is due to the problem
of the fixed-order NRQCD calculation that may not be applicable for the region
with small $p_T$ ($p_T\sim 5 ~\mbox{GeV}$) and large forward rapidity
$(2.5<y<4.5)$. In comparison, the prediction of molecule production mechanism
for $X(3872)$ is inconsistent with both $p_T$ distributions and total cross
sections of CMS and ATLAS, and the total cross section of CDF.
