Intertwined order and holography: the case of the parity breaking pair density wave
We present a minimal bottom-up extension of the Chern-Simons bulk action for
holographic translational symmetry breaking that naturally gives rise to pair
density waves. We construct stationary inhomogeneous black hole solutions in
which both the U(1) symmetry and spatially translational symmetry are
spontaneously broken at finite temperature and charge density. This novel
solution provides a dual description of a superconducting phase intertwined
with charge, current and parity orders.Comment: v3: Revised version in which the rules of effective field theory are

Hunting for a scalar glueball in exclusive B decays
Using flavor SU(3) symmetry for the light quarks validated by the available
experimental data, we propose an intuitive way to hunt for a scalar glueball in
B decays. In the presence of mixing between the glueball and ordinary scalar
mesons, we explore the extraction of the mixing parameters. In particular, we
discuss the implication from the recently available experimental data and show
the sensitivities of B decays as a probe to the scalar structures. The future
Super KEKB factory would allow access to establishing the mixing pattern among
the scalars, and possibly allow one to disentangle the long-standing puzzle
concerning the existence and mixings of the scalar glueball predicted by QCD.Comment: 5 pages, 1 figur

Competition between s-wave order and d-wave order in holographic superconductors
We study competition between s-wave order and d-wave order through two
holographic superconductor models. We find that once the coexisting phase
appears, it is always thermodynamically favored, and that the coexistence phase
is narrow and one condensate tends to kill the other. The phase diagram is
constructed for each model in terms of temperature and the ratio of charges of
two orders. We further compare the behaviors of some thermodynamic quantities,
and discuss the different aspects and identical ones between two models.Comment: 3 figures added, accepted by JHE

Gluon Fusion induced Zg and Zgg Productions in the Standard Model at the LHC
We report calculations of the gluon induced Zg and Zgg productions in the
Standard Model at the LHC operating at both 7 TeV and 14 TeV collision energy.
We present total cross sections and differential distributions of the processes
and compare them with the leading and next-to-leading order QCD pp -> Z+1 jet,
Z+2 jets results. Our results show that the gluon induced Zg and Zgg
productions contribute to pp -> Z+1 jet, Z+2 jets at 1% level.Comment: 8 pages, 5 figure
