A note on membrane interactions and the scalar potential [PDF]
Journal of High Energy Physics, 2020 We compute the tree-level potential between two parallel p-branes due to the exchange of scalars, gravitons and (p+1)-forms. In the case of BPS membranes in 4d N $$ \mathcal{N} $$ = 1 supergravity, this provides an interesting reinterpretation of the ...

Bumping into the Species Scale with the Scalar Potential
Fortschritte Der Physik, 2023 AbstractAs a quantum gravity cut‐off, the species scale gets naturally compared to the energy scale of a scalar potential V in an EFT. In this note, the species scale, its rate and their field dependence, to those of a scalar potential is compared. To that end, a string compactification leading to a scalar potential with the same properties as the ...

Effects of modified woods saxon potential on quantum dynamics of spin 0 scalar particle in a cosmic string spacetime [PDF]
Scientific ReportsIn this study, we investigate the quantum dynamics of spin-0 scalar particles interacting with both scalar and vector potentials in the background of a cosmic string space-time, under the influence of a quantum flux field.

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.

Effective potential of scalar–tensor gravity [PDF]
Classical and Quantum Gravity, 2020 Abstract Effective potential of a scalar field induced by weak gravity is studied. The set of operators providing the leading contribution and preserving the second order of field equations is found. It is shown that only a mass term and a specific Brans–Dicke-like interaction are relevant within such a setup.

Generic scalar potentials in geometric scalar gravity [PDF]
Journal of Theoretical and Applied Physics, 2016 We discuss a generic form of the scalar potential appearing in the geometric scalar theory of gravity. We find the conditions on the potential by considering weak and strong gravity. The modified black hole solutions are obtained for generic potentials and the inverse problems on a black hole and on a spherical body (`pseudo-gravastar') are ...

Composite scalar bosons masses: Effective potential versus Bethe-Salpeter approach
Physics Letters B, 2023 Ten years ago the 125 GeV Higgs resonance was discovered at the LHC [1,2], if this boson is a fundamental particle or a particle composed of new strongly interacting particles is still an open question.

Physics Letters B, 2022 We investigate the effect of peculiar velocities of inhomogeneities and the spatial curvature of the universe on the shape of the gravitating potential. To this end, we consider scalar perturbations of the FLRW metric.
