Isospin-conserving hadronic decay of the Ds1(2460) into Dsπ+π-

Meng-Na Tang, Yong-Hui Lin, Feng-Kun Guo, Christoph Hanhart, Ulf-G. Meissner

Summary: The internal structure of charm-strange mesons D-s0*(2317) and D-s1(2460) is being extensively studied. Their narrow widths are due to their dominant decay through isospin-breaking hadronic channels. The decay of D-s1(2460) can also occur through hadronic final states with isospin conservation, but is strongly suppressed due to phase space limitations. By considering the Ds1(2460) as a D*K hadronic molecule, we find that the predicted partial widths and the pi(+)pi(-) invariant mass distribution are consistent with experimental measurements, and suggest possible ways to distinguish between the hadronic molecular and compact state pictures for the D-s1(2460)(+). Predictions for B-s1(0) -> B-s(0) pi(+) pi(-) are also made.

Understanding the 0++ and 2++ charmonium(-like) states near 3.9 GeV

Teng Ji, Xiang-Kun Dong, Miguel Albaladejo, Meng-Lin Du, Feng-Kun Guo, Juan Nieves, Bing-Song Zou

Summary: We propose that the X(3915) observed in the J/psi x channel is the same as the chi(c2)(3930), while the X(3960) observed in the Ds+Ds- channel is an S-wave Ds+Ds- hadronic molecule. Additionally, we find that the B+ -> D+D-K+ component with J(PC) = 0(++) assigned to the X(3915) in the current Review of Particle Physics has the same origin as the X(3960) with a mass of around 3.94 GeV. By analyzing available data in the D (D) over bar and Ds+Ds- channels from B decays and gamma gamma fusion reaction, considering both the D (D) over bar -D-s(D) over bar (s)-D*(D) over bar*-D-s*(D) over bar (s)* coupled channels with 0(++) and a 2(++) state introduced additionally, we find that all the data in different processes can be simultaneously well reproduced, and four hidden-charm scalar molecular states with masses around 3.73, 3.94, 3.99, and 4.23 GeV are produced. These results may deepen our understanding of the spectrum of charmonia and the interactions between charmed hadrons.

On the eta(1)(1855), pi(1)(1400) and pi(1)(1600) as Dynamically Generated States and Their SU(3) Partners

Mao-Jun Yan, Jorgivan M. M. Dias, Adolfo Guevara, Feng-Kun Guo, Bing-Song Zou

Summary: We interpret the newly observed eta(1)(1855) resonance with exotic J(PC) = 1(-+) quantum numbers in the I = 0 sector, as a dynamically generated state from the interaction between lightest pseudoscalar mesons and axial-vector mesons. The interaction is derived from the lowest order chiral Lagrangian, which is then unitarized using the Bethe-Salpeter equation, according to the chiral unitary approach. We evaluate the decays of eta(1)(1855) into eta eta' and K (K) over bar*pi channels, and find that the latter has a larger branching fraction. Furthermore, we investigate its SU(3) partners and suggest searching for two additional eta(1) exotic mesons with masses around 1.4 and 1.7 GeV.

New insights into the nature of the Λ(1380) and Λ(1405) resonances away from the SU(3) limit

Feng-Kun Guo, Yuki Kamiya, Maxim Mai, Ulf-G. Meissner

Summary: Starting from the SU(3) limit, the nature of the dynamically generated resonances Lambda(1380), Lambda(1405) and Lambda(1680) were studied as the masses of pion and kaon were tuned to their physical values. It was found that the accidental symmetry of the two octets due to the leading order Weinberg-Tomozawa term is broken by the next-to-leading order terms. Most interestingly, an interchange of the two trajectories of Lambda(1380) and Lambda(1405) away from the SU(3) limit at next-to-leading order was observed.

Summary: This White Paper aims to emphasize the significant advantages in the scientific progress achieved by the EIC. High luminosity operation is highly desirable as it allows for faster production and collection of scientific results. This becomes crucial for programs that require months or even years of operation at lower luminosity.

Radiative decays of the spin-2 partner of X(3872)

Pan-Pan Shi, Jorgivan M. Dias, Feng-Kun Guo

Summary: It is expected that X(3872) has a spin-2 partner, X2, with a mass below the D*D over bar * threshold. The structure with a mass of (4014.3 & PLUSMN;4.0 & PLUSMN; 1.5) MeV reported by Belle Collaboration is considered a good candidate for X2. The radiative decay widths and signal of X2 in two-photon collisions are estimated, and the search for X2 signal in the γJ/ψ invariant mass distribution is suggested.

Chromopolarizabilities of fully heavy baryons

Xiang-Kun Dong, Feng-Kun Guo, Alexey Nefediev, Jaume Tarrus Castella

Summary: We calculate the chromopolarizabilities of the fully heavy baryons 52QQQ0 in the framework of potential nonrelativistic quantum chromodynamics and find that it is 2.6 times the chromopolarizability of the quarkonium Q over bar Q with the same heavy quark flavor. This result provides an order-of-magnitude estimate for these quantities and their dependence on various factors like heavy quark mass and strong coupling constant. The implication of our findings is the possible existence of near-threshold states composed of pairs of fully heavy baryons.

Hadronic decays of the heavy-quark-spin molecular partner of T cc

Zhao-Sai Jia, Mao-Jun Yan, Zhen-Hua Zhang, Pan-Pan Shi, Gang Li, Feng-Kun Guo

Summary: Based on the hypothesis that the Tcc discovered at LHCb is a D0=D0 hadronic molecule, we studied the partial width of its heavy quark spin partner, the Tcc, as a D⠂0D⠂0 shallow bound state. We considered the contributions of the D⠂D and D⠂pi final state interactions and found that the rescattering corrections can significantly affect the decay widths. The total width of the Tcc was predicted to be about 41 keV.

Emergence of heavy quark spin symmetry breaking in heavy quarkonium decays

V. Baru, E. Epelbaum, A. A. Filin, C. Hanhart, A. V. Nefediev

Summary: Heavy-quark spin symmetry applies to the direct decay of heavy quarkonia, but can be overcome in the presence of multiquark intermediate states. The violation of HQSS can be balanced by the narrowness of the intermediate states, resulting in equal transition strengths into final states with different total heavy quark spins. Spin symmetry is restored when the mass of a heavy quark becomes infinite.

Spin-orbit amplitudes for decays with arbitrary spin

Xiao-Yu Li, Xiang-Kun Dong, Hao-Jie Jing

Summary: This paper proposes a method to construct decay amplitudes for particles with arbitrary spins in the orbital and spin coupling scheme. The angular dependence of the 1 -> 2 decay is encoded in the angular momentum part, and the spins of daughter particles are coupled in the rest frame of the mother particle. For sequential decay, the total amplitude is constructed by evaluating the 1 -> 2 amplitudes in the rest frame of their own mother particles and then transforming them to a common frame.

D+D- hadronic atom and its production in pp and p(p)over-bar collisions

Pan-Pan Shi, Zhen-Hua Zhang, Feng-Kun Guo, Zhi Yang

Summary: In this study, the properties and production of the ground-state D+D- hadronic atom A(D+D-), called dionium, are investigated. The mass, binding energy, and decay width of the dionium are predicted using nonrelativistic effective field theory. The estimated cross-sections for the prompt and direct production of the dionium provide valuable information on charmed meson interaction and understanding charmoniumlike states.
