Large- and renormalization group constraints on parity-violating low-energy coefficients for three-derivative operators in pionless effective field theory
Son T. Nguyen, Matthias R. Schindler, Roxanne P. Springer +1
We extend from operators with one derivative to operators with three derivatives the analysis of two-body hadronic parity violation in a combined pionless effective field theory (E…
Using the decay ψ(4160) -> X(3872) γ to probe the molecular content of the X(3872)
Arman Margaryan, Roxanne P Springer
The X(3872) has non-charmonium-like properties, such as decay processes that seem to violate isospin, and a mass that lies unexpectedly close to the neutral-D-plus-neutral-D-excite…
Radiative Decays X(3872) -> psi(2S)+gamma and psi(4040) -> X(3872)+gamma in Effective Field Theory
Thomas Mehen, Roxanne Springer
Heavy hadron chiral perturbation theory (HHchiPT) and XEFT are applied to the decays X(3872) -> psi(2S) + gamma and psi(4040) -> X(3872) + gamma under the assumption that the X(387…
On the scattering of D and D* mesons off the X(3872)
David L. Canham, H. -W. Hammer, Roxanne P. Springer
Both the mass (just below the D^{*0}Dbar^0 threshold) and the likely quantum numbers (J^{PC}=1^{++}) of the X(3872) suggest that it is either a weakly-bound hadronic ``molecule'' o…
Even- and Odd-Parity Charmed Meson Masses in Heavy Hadron Chiral Perturbation Theory
Thomas Mehen, Roxanne Springer
We derive mass formulae for the ground state, J^P = 0^- and 1^-, and first excited even-parity, J^P = 0^+ and 1^+, charmed mesons including one loop chiral corrections and O(1/m_c)…
Heavy-Quark Symmetry and the Electromagnetic Decays of Excited Charmed Strange Mesons
Thomas Mehen, Roxanne P. Springer
Heavy-hadron chiral perturbation theory (HHPT) is applied to the decays of the even-parity charmed strange mesons, D_{s0}(2317) and D_{s1}(2460). Heavy-quark spin symmetry predi…
