Doubly charmed molecular pentaquarks

چکیده
We perform a systematic exploration of the possible doubly charmed molecular pentaquarks composed $\Sigma_c^{(*)}D^{(*)}$ with one-boson-exchange potential model. After taking into account $S-D$ wave mixing and coupled channel effects, we predict several pentaquarks, which include $\Sigma_cD$ $I(J^P) = 1/2(1/2^-)$, $\Sigma_c^*D$ $1/2(3/2^-)$, $\Sigma_cD^*$ $1/2(1/2^-)$, $1/2(3/2^-)$. The state $3/2(1/2^-)$ may also be suggested as candidates pentaquarks. states can searched for by analyzing $\Lambda_cD\pi$ invariant mass spectrum bottom baryon $B$ meson decays. in $\Lambda_cD^*\pi$, $\Lambda_cD\pi\pi$ $\Lambda_cD\pi\gamma$. Since width $\Sigma_c^*$ is much larger than that $D^*$, $\Sigma_c^*D\rightarrow \Lambda_cD\pi$ will dominant decay mode. sincerely hope these pentaqurks LHCb or BelleII collaboration near future.

Doubly Charmed Baryons in Compass
The search for doubly charmed baryons has been a topic for COMPASS from the beginning. Requiring however a complete spectrometer and highest possible trigger rates this measurement has been postponed. The scenario for such a measurement in the second phase of COMPASS is outlined here. First studies of triggering and simulation of the setup have been performed. New rate estimates based on recent...
متن کاملCharmed strange pentaquarks in the large Nc limit.
The properties of pentaquarks containing a heavy anti-quark and strange quarks are studied in the bound state picture. In the avor SU(3) limit, there are many pentaquark states with the same binding energy. When the SU(3) symmetry breaking e ects are included, however, three states become particularly stable due to a \Gell-Mann{Okubo mechanism". They are the Qsuud and Qsudd states discussed by ...
متن کاملSearch for charmed pentaquarks in high energy neutrino interactions
Several experiments have reported the existence of a bound state of five quarks with s̄ content, knows as Θ. However, the existence of pentaquark states with charm quark content is still controversial. In this paper we focus on weakly decaying charmed pentaquarks and show how they can be searched for in high energy anti-neutrino interactions. We discuss their possible mass and branching ratios a...
متن کاملU-Spin Symmetry in Doubly Cabibbo-Suppressed Charmed Meson Decays
We prove a U-spin amplitude triangle relation among doubly Cabibbosuppressed (DCS) charmed meson decays, D → Kπ, D → Kπ and D s → KK, congruent to an isospin relation among corresponding Cabibbo-favored (CF) decays. U-spin breaking in relative phases between CF and DCS amplitudes affects time-dependent studies of D −D0 mixing. Comparison of final state phase patterns in DCS and CF amplitude tri...
