Renormalization for a Scalar Field in an External Scalar Potential [PDF]
Symmetry, 2018 The Pauli–Villars regularization procedure confirms and sharpens the conclusions reached previously by covariant point splitting. The divergences in the stress tensor of a quantized scalar field interacting with a static scalar potential are isolated into a three-parameter local, covariant functional of the background potential.

Complex scalar fields in scalar-tensor and scalar-torsion theories
Modern Physics Letters A, 2022 In this paper, we investigate the cosmological dynamics in a spatially flat Friedmann–Lemaître–Robertson–Walker geometry in scalar-tensor and scalar-torsion theories where the nonminimally coupled scalar field is a complex field. We derive the cosmological field equations and we make use of dimensionless variables in order to determine the stationary ...

Spontaneous scalarization of a conducting sphere in Maxwell-scalar models [PDF]
, 2021 We study the spontaneous scalarization of a standard conducting charged sphere embedded in Maxwell-scalar models in flat spacetime, wherein the scalar field ϕ is nonminimally coupled to the Maxwell electrodynamics.

Atomic Ionization by Scalar Dark Matter and Solar Scalars [PDF]
Physical Review Letters, 2021 We calculate the cross-sections of atomic ionization by absorption of scalar particles in the energy range from a few eV to 100 keV. We consider both nonrelativistic particles (dark matter candidates) and relativistic particles which may be produced inside Sun.

Physical Review D, 2019 We conjecture that there exists a scalar bound state for every pair of fundamental fermions at a UV (`composite') scale, $Λ\gg v_{\text{weak}}$. This implies a large number of universally coupled, sub-critical Higgs doublets. All but the Standard Model Higgs are `dormant,' with large positive squared masses and each receives a small vacuum expectation ...

MIXING OF SCALAR GLUEBALL AND SCALAR QUARKONIA [PDF]
High Energy Physics, 2007 The isosinglet scalar mesons $f_0(1710)$, $f_0(1500)$, $f_0(1370)$ and their mixing are studied. Two recent lattice results are employed as the starting point; one is the approximate SU(3) symmetry in the scalar sector above 1 GeV for the connected insertion part without $q\bar q$ annihilation, and the other is the scalar glueball mass at 1710 MeV in ...

International Journal of Modern Physics B, 1994 We determine the excitations and S matrix of an integrable isotropic antiferromagnetic quantum spin chain of alternating spin 1/2 and spin 1. There are two types of gapless one-particle excitations: the usual spin 1/2 (“spinor”) kink, and a new spin 0 (“scalar”) kink.

SCALAR–SCALAR BOUND STATE IN NONCOMMUTATIVE SPACE [PDF]
Modern Physics Letters A, 2001 Bethe–Salpeter equation in the noncommutative space for a scalar–scalar bound state is considered. It is shown that in the nonrelativistic limit, the effect of spatial noncommutativity appears as if there exists a magnetic dipole moment coupled to each particle.

Strict Benson proper-ε-efficiency in vector optimization with set-valued maps [PDF]
Yugoslav Journal of Operations Research, 2015 In this paper the notion of Strict Benson proper-ε-efficient solution for a vector optimization problem with set-valued maps is introduced. The scalarization theorems and ε-Lagrangian multiplier theorems are established under the assumption of ...
