چکیده
Hidden-charm pentaquark-like PψsΛ(4459)0 and PψsΛ(4338) resonances are studied in a constituent quark model as molecular meson-baryon structures. Such states found the JP(I)=12−(0) channel with masses widths compatible experimental measurements coupled-channels calculation all parameters constrained from previous studies. Other candidates explored JP=12−, 32− 52− channels charm bottom sectors, isospins 0 (PψsΛ PϒsΛ) 1 (PψsΣ PϒsΣ). Additionally, formalism is extended to study PψssN (PϒssN) pentaquarks, where eight predicted D¯sΞc molecules I=12, for sector nine BsΞb one.

Predictions of charged charmoniumlike structures with hidden-charm and open-strange channels.
We propose the initial single chiral particle emission mechanism, with which the hidden-charm dikaon decays of higher charmonia and charmoniumlike states are studied. Calculating the distributions of differential decay width, we obtain the line shape of the J/ψK(+) invariant mass spectrum of ψ(i)→J/ψK(+)K(-), where ψ(i)=ψ(4415), Y(4660), and ψ(4790). Our numerical results show that there exist ...
متن کاملCharm fragmentation and excited charm and charm-strange mesons at ZEUS
Charm hadrons were produced copiously in ep collisions with a centre-of-mass energy of 318GeV at HERA providing a means to study charm hadronisation. During first phase of the HERA operation (1992-2000), the ZEUS collaboration accumulated data sample corresponding to an integrated luminosity of ∼ 120 pb. Measurements of the D, D, D and Λc production a with the HERA I data were used to determine...
متن کاملCharm 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 theory defines strange vowel sets
A typical grammar uses several distinct components which interact in a complicated fashion, providing a description of a language at a very high level. Although theoretical development can continue by focusing attention on only a small portion of the formalism at a time, confident prediction and validation of the correct coverage of any nontrivial grammar (and hence the global validity of the t...
