Scalar Extension of Bicoalgebroids [PDF]
After recalling the definition of a bicoalgebroid, we define comodules and modules over a bicoalgebroid. We construct the monoidal category of comodules, and define Yetter--Drinfel'd modules over a bicoalgebroid. It is proved that the Yetter--Drinfel'd category is monoidal and pre--braided just as in the case of bialgebroids, and is embedded into the ...

Scalar mesons and scalar gluonium
We investigate the mixing of scalar mesons (S*, ɛ) with gluonium in the context of a potential model. We calculate the masses of the scalars and the branching ratios to ππ,KK, ηη and ηη′. The model can accomodate the stateG(1.59) and explain its peculiar rates. We also investigate other possibilities for gluonium mass and branching ratios and find that

We describe a new realization of supersymmetry, called scalar supersymmetry, acting in spaces of differential forms (bi-spinors), where transformation parameters are Lorentz scalars instead of spinors. The realization is related but is not reducible to the standard supersymmetry.

Leptonic Scalars versus Scalar Leptons [PDF]
The notion of scalars having lepton number, i.e. leptonic scalars, is discussed without supersymmetry, where scalar leptons reside. It is shown how dark parity comes from lepton parity, as well as its possible origin from grand unification. Two specific phenomenological applications to dark matter are described.

I argue that in certain chiral gauge theories composite scalars associated with chiral symmetry breaking can be light (i.e. lighter than naive scaling from QCD would suggest) without any fine-tuning. These scalars will be even lighter in chiral gauge theories that produce chiral symmetry breaking without confinement.

Spectrum of scalar-scalar bound states [PDF]
An exactly solvable, Barbieri-Remiddi-like equation for bound states of two scalar constituents interacting with massless vector particles is presented for both stable and unstable particles. With the help of this equation the bound state spectrum is calculated to O({alpha}{sup 4}) for a SU(N) non-Abelian gauge theory.

Tachyonic instability and spontaneous scalarization in parameterized Schwarzschild-like black holes
We study the phenomenon of spontaneous scalarization in parameterized Schwarzschild-like black holes. Two metrics are considered, the Konoplya–Zhidenko metric and the Johannsen–Psaltis metric.

Certified Adaptive Triangulation Sampling for Deterministic Pareto-Surface Reconstruction
Many deterministic multi-objective optimization methods generate Pareto outcomes by repeatedly solving scalarized subproblems for different preference or reference vectors.

Charged qOS-extremal black hole and its scalarization by entropy function approach
We investigate scalarization of charged quantum Oppenheimer–Snyder extremal (cqOSe)-black hole described by mass M, quantum parameter $$\alpha $$ α and magnetic charge P in the Einstein–Gauss–Bonnet-scalar theory with a nonlinear electrodynamics term ...
