Summary: In this study, we investigate the magnetic and quadrupole moments of the Bc-like ground state tetraquarks using the molecular and diquark-antidiquark pictures. Numerical analysis is conducted with different forms of interpolating currents and photon distribution amplitudes. The obtained results show significant differences between the two pictures, and the nonzero but small quadrupole moments indicate non-spherical charge distributions. Experimental measurements of the magnetic moments can provide insights into the internal structure of these states.

Summary: Using lightcone sum rules, the magnetic dipole moment of the X-1(2900) state with quantum numbers J(P) = 1(-) is determined to be mu X-1 = 0.79(-0.39)(+0.36) mu N. The measurement of magnetic moments provides valuable information about the charge and magnetization distributions inside hadrons, and the discovery of X-0(2900) and X-1(2900) opens up new possibilities for studying exotic states.

Summary: This article revisits the electric, magnetic, and toroidal dipolar moments in metamaterial structure and presents a flatland design for generating a toroidal dipolar response. Through numerical analysis and electromagnetic multipole theory, it is found that the earlier symmetric unit cell design cannot produce a toroidal dipolar moment. A new planar metasurface design is proposed, which shows a higher scattered power and a dominant toroidal response when excited by a TM-polarized electromagnetic wave.

Summary: This paper presents that the long-standing discrepancy of the muon anomalous magnetic moment may be a hint of new physics beyond the standard model. Experimental tests can be conducted at a muon collider to investigate the contribution of heavy new physics, and even measure the g - 2 operator directly. The most challenging scenario can be effectively tested at a future muon collider.

Summary: A set of Steroidal Molecular Rotors (SMRs) were successfully synthesized and characterized, and it was found that using stators with lower dipole moment can lower the rotational activation energy. Results from solid-state NMR revealed that one of the compounds indeed exhibits fast rotational motion within a crowded crystallographic environment.

Summary: The intrinsic characteristics of organic semiconductor-based hole transport materials play a crucial role in determining the performance of perovskite photovoltaic cells. Understanding the excited state properties and aggregation behavior of organic HTMs is essential for improving PV efficiency.

Summary: Motivated by improved limits on electric dipole moments (EDMs), this paper revisits the mechanism of transmitting CP violation from a heavy fermion to a light one. The authors find additional contributions at a lower order that were missing before, leading to an increase in the results. Consequently, they improve bounds on some EDMs and update indirect limits on others.

Summary: The study investigated the spectral behavior of 6AQ in different solvents, showing solvatochromism with increasing Stokes shift and a more polar excited state possibly due to a change in geometry and involvement of pi -> pi* transition. The dipole moments of the ground state and excited state were determined, with the excited state having a higher dipole moment possibly due to intramolecular charge transfer. The molecule exhibited reasonable band-gap energy and good blue CIE coordinates, suggesting potential applications in optoelectronics.

Summary: The study demonstrates that the nanocrystal system coupled via dipolar interaction shows an anti-crossing behavior under an external applied magnetic field, resulting in a Lorentz-shaped photoluminance intensity signal with an unusual dip-shape at the zero detuned states. This dip-shape corresponds to the point where crossing would occur in the absence of dipolar interaction.

Summary: Motivated by the discovery of the tetraquark T-cc(+), this study investigates the magnetic dipole moments of the possible single and double strange partners, T-QQqs and T-QQss, using the QCD light-cone sum rules. The results show significant differences in the magnetic dipole moments obtained using different diquark-antidiquark structures. The magnetic dipole moment is a valuable tool for studying the inner structures of hadrons governed by the quark-gluon dynamics of QCD.

Summary: This study presents the first direct calculation on the gravitational form factors (GFFs) of the N -> Delta transition using the QCD light-cone sum rules. The matrix element of the quark part of the energy momentum tensor current is parameterized in terms of five independent conserved and four independent non-conserved GFFs. The results show that the behavior of the form factors with respect to Q(2) can be described by multipole fit functions. These results can be tested by other phenomenological models and future related experiments, including Lattice QCD.

Summary: In this study, the doubly charged scalar resonance Tcas0(2900)++ is considered as a hadronic molecule composed of vector mesons. The mass, current coupling, and width of the molecule M = D*+K*+ are calculated. Using the QCD two-point sum rule method, taking into account the vacuum expectation values, the spectroscopic parameters of M, including its mass and current coupling, are determined. The width of M is obtained by calculating the partial widths of its decay channels. The predicted mass and width of the hadronic molecule M suggest it as a possible candidate of the resonance Tacs0(2900)++.

Summary: A candidate triple strange pentaquark state, P-csss, is investigated through its strong decay channel P-csss -> C2-J=y/. Two possible interpolating currents with spin-parity JP 1/4 1 - are used to calculate the relevant strong coupling constants. The chosen currents couple to both positive and negative parity states simultaneously, and the decay widths are obtained for both parities. These results may provide insights into future experimental observations and characterization of such candidate states.

Summary: We investigate the hidden charm-strange scalar tetraquark cc over bar ss over bar by calculating its spectral parameters and width, and compare the results with the recently discovered resonance X(3960) in the LHCb experiment. We model the tetraquark as a diquark-antidiquark state X = [cs][c over bar s over bar ] with spin-parities JPC = 0++. The mass and current coupling of X are calculated using QCD two-point sum rules, and the width is estimated via decay channels X -> D+s D-s and X -> eta c eta(0). Comparing the obtained results with experimental data, we conclude that the resonance X(3960) can be considered as a candidate to a scalar diquark-antidiquark state.

Summary: Spectroscopic parameters and widths of the fully open-flavor axial-vector and pseudoscalar tetraquarks XAV and X-PS were calculated using QCD sum rule methods. The masses and current couplings were determined through two-point sum rule computations, taking into account various vacuum condensates. Decay modes were considered to evaluate the full width of XAV and X-PS. By employing the QCD light-cone sum rule method and soft-meson approximation, the partial widths of these decay modes were determined, providing predictions that may be useful in future experimental studies of multiquark hadrons.

Summary: The spectroscopic parameters and electromagnetic form factor of the strange particle kaon are investigated in both vacuum and a medium with finite density. The study provides consistent results with existing experimental data for the vacuum mass and decay constant of the kaon. The behavior of the kaon's electromagnetic form factor is found to be in agreement with predictions from lattice QCD and the Nambu-Jona-Lasinio model, as well as with experimental results for the vacuum radius. The study also explores the effects of higher densities on various parameters and provides comparisons with predictions from other models and approaches. These findings are important for future experimental and theoretical studies in both vacuum and dense media.
