Charm and hidden charm scalar mesons in the nuclear medium
We study the renormalization of the properties of the low lying charm and hidden charm scalar mesons in a nuclear medium, concretely of the D s0 (2317), D 0 (2400) and the theoretical hidden charm state X(3700). We find that for the D s0 (2317), with negligible width at zero density, the width becomes about 100 MeV at normal nuclear matter density, while in the case of the X(3700) the width bec...
متن کاملCharm and Hidden Charm Scalar Resonances in Nuclear Matter
We study the properties of the scalar charm resonances Ds0(2317) and D0(2400), and the theoretical hidden charm state X(3700) in nuclear matter. We find that for the Ds0(2317) and X(3700) resonances, with negligible and small width at zero density, respectively, the width becomes about 100 MeV and 200 MeV at normal nuclear matter density, accordingly. For D0(2400) the change in width is relativ...
متن کاملCharm in the Nucleon
A next-to-leading order analysis of inelastic electroproduction of charm is performed using an interpolating scheme which maps smoothly onto massless QCD evolution at large Q2 and photon–gluon fusion at small Q2. In contrast with earlier analyses, this scheme allows the inclusion of quark and target mass effects and heavy quark thresholds, as well as possible non-perturbative, or intrinsic, cha...
متن کاملCP violation in charm
Charm transitions play a unique dual role in the modern investigations of flavor physics. They provide valuable supporting measurements for studies of CPviolation in B-decays, such as formfactors and decays constants, as well as outstanding opportunities for indirect searches for physics beyond the Standard Model (SM). It must be noted that in many dynamical models of new physics the effects of...

mD −mA −mB 2 − 4mAmB within the kinematically allowed limits, and λ = 0 outside. In the above expression, aie iδi describe complex contributions to the total decay amplitude. In the simplest case, aie iδi are complex Breit-Wigner distributions (or similar e.g. the Flatté distribution [3]) describing individual particle resonances, with additional factors taking into account angular momentum con...
