The hidden charm pentaquarks are the hidden color-octet uud baryons?
Physics Letters B, 2017 The I(JP)=12(12−), 12(32−), and 12(52−) uudcc‾ pentaquarks are investigated by the quark cluster model. This model, which reproduces the mass spectra of the color-singlet S-wave q3 baryons and qq‾ mesons, also enables us to evaluate the quark interaction

Mixing of 1/2^- Octets under SU(3) Symmetry [PDF]
Mod.Phys.Lett.A23:703-710,2008, 2007 We investigate the J^p=1/2^- baryons in the octets based on flavor SU(3) symmetry. Since baryons with same quantum numbers can mix with each other, we consider the mixing between two octets before their mixing with the singlet. Most predicted decay widths are consistent with the experimental data, and meanwhile we predict two possible $\Xi$ mass ranges

Advanced Healthcare Materials, EarlyView.This study investigates the role of triply periodic minimal structures in load bearing bone tissue engineering applications. Research uses a combination of mechanical testing, material characterization, and in vitro tests to study the impact of TPMS lattice structures (gyroid, lidinoid and split‐P).

Neutron Electric Dipole Moment from colored scalars⋆
EPJ Web of Conferences, 2014 We present new contributions to the neutron electric dipole moment induced by a color octet, weak doublet scalar, accommodated within a modified Minimal Flavor Violating framework.

Quantum coherence, top transverse polarisation and the Tevatron asymmetry AFBℓ
Physics Letters B, 2014 We revisit the relation between the asymmetries AFB and AFBℓ in tt¯ production at the Tevatron, using as new physics benchmark a colour octet. We find that AFBℓ receives large contributions from the interference between λ=±1/2 top helicity states, which ...

Color-Octet-Electroweak-Doublet Scalars and the CDF Dijet Anomaly
, 2011 We study the phenomenology of color-octet scalars in the (8, 2)1/2 representation in the context of the 3.2\sigma excess, in the dijet invariant mass spectrum of the W+jj final state, recently observed by the CDF collaboration.

Large-Nc operator analysis of hyperon–nucleon interactions in SU(3) chiral effective field theory
Physics Letters B, 2019 We study octet–octet baryon (JP=12+) contact interactions in SU(3) chiral effective field theory by using large-Nc operator analysis. By applying the 1/Nc expansion of the Hartree Hamiltonian, we find 15 operators in the octet–octet baryon potential ...

Octet lattice-based plate for elastic wave control
Scientific Reports, 2022 Motivated by the importance of lattice structures in multiple fields, we numerically investigate the propagation of flexural waves in a thin reticulated plate augmented with two classes of metastructures for wave mitigation and guiding, namely ...

SU(5) Octet Scalar at the LHC [PDF]
Phys. Rev. D 89, 095011 (2014), 2014 Color scalars are salient features of non-minimal SU(5) model, where Higgs sector is extended by 45-dimensional multiplet. We show that gauge coupling unification can be realized in this model with TeV octet scalar and intermediate (~10^6 GeV) color-triplet scalar at scale larger than 10^{15} GeV.
