Color Octet Scalar Bound States at the LHC
Chul Kim, Thomas Mehen
One possible extension of the Standard Model scalar sector includes SU(2)_L doublet scalars that are color octets rather than singlets. We focus on models in which the couplings to…
Comparing different freeze-out scenarios in azimuthal hadron correlations induced by fast partons
R. Bryon Neufeld
I review the linearized hydrodynamical treatment of a fast parton traversing a perturbative quark-gluon plasma. Using numerical solutions for the medium's response to the fast part…
In-medium modification of P-wave charmonia from QCD sum rules
Young-Ho Song, Su Houng Lee, Kenji Morita
We investigate the changes of the masses and widths of and in hot gluonic matter near and in nuclear medium using QCD sum rules. As in the previous works fo…
Hadronic Decays of the X(3872) to chi_{cJ} in Effective Field Theory
Sean Fleming, Thomas Mehen
The decays of the X(3872) to P-wave quarkonia are calculated under the assumption that it is a shallow bound state of neutral charmed mesons. The X(3872) is described using an effe…
Leading SU(3) breaking in lightcone distribution amplitudes
Chul Kim, Adam K. Leibovich
The lightcone formalism including SU(3) breaking effects for the light pseudoscalar mesons is studied using soft-collinear effective theory (SCET), where the conformal symmetries n…
Nonperturbative Charming Penguin Contributions to Isospin Asymmetries in Radiative B decays
Chul Kim, Adam K. Leibovich, Thomas Mehen
Recent experimental data on the radiative decays B -> V gamma, where V is a light vector meson, find small isospin violation in B -> K^* gamma while isospin asymmetries in B -> rho…
