Decay Widths of X(1835) as Nucleon-Antinucleon Bound State
D. Samart, Y. Yan, Th. Gutsche +1
Partial decay widths of various decay channels of the X(1835) are evaluated in the 3P0 quark model, assuming that the X(1835) is a nucleon-antinucleon bound state. It is found that…
CTA Sensitivity on TeV scale Dark Matter Models with Complementary Limits from Direct Detection
C. Duangchan, C. Pongkitivanichkul, P. Uttayarat +8
With ever increasing pressure from collider physics and direct detection experiments, particle physics models of TeV scale dark matter are gaining more attention. In this work, we…
Analysis of excited quark propagator effects on neutron charge form factor
X. Y. Liu, A. Limphirat, K. Xu +3
The charge form factor and charge radius of neutron are investigated in the perturbative chiral quark model (PCQM) with considering both the ground and excited states in the quark…
Combined large- and heavy-quark operator analysis of 2-body meson-baryon counterterms in the chiral Lagrangian with charmed mesons
M. F. M. Lutz, D. Samart, A. Semke
The chiral SU(3) Lagrangian with pseudoscalar and vector mesons and with the octet and decuplet baryons is considered. The leading two-body counter terms involving two baryon f…
Combined large-N_c and heavy-quark operator analysis for the chiral Lagrangian with charmed baryons
M. F. M. Lutz, D. Samart, Y. Yan
The chiral Lagrangian with charmed baryons of spin and is analyzed. We consider all counter terms that are relevant at next-to-next-to-next-to-leadi…
