Redshift Suppression of Nonlinear Scalar Fields in Accelerating FLRW Spacetimes
Mirda Prisma Wijayanto, Emir Syahreza Fadhilla, Ryan Sugihakim +3
We study small--data solutions of a nonlinear scalar field equation on spatially flat --dimensional FLRW spacetimes (). In conformal time the field satisfies a dampe…
Radiative Maxwell Scattering on Slowly Rotating Weakly Charged Kerr-Newman Black Holes
Bobby Eka Gunara, Mulyanto, Emir Syahreza Fadhilla +1
We study real source-free Maxwell fields on slowly rotating, weakly charged Kerr-Newman exteriors and set up a finite-energy scattering theory after removal of the stationary Coulo…
Coulomb Sectors and Scattering for Maxwell-Higgs Fields on Schwarzschild and Slowly Rotating Kerr Backgrounds
Bobby Eka Gunara, Mulyanto, Fiki Taufik Akbar
We develop a small-data Maxwell--Higgs theory on Schwarzschild and slowly rotating Kerr black-hole exteriors for gauge-invariant nonnegative self-interactions near the trivial vacu…
Deep Neural Networks for Heavy Lepton-Flavor-Violating Higgs Searches at the LHC
Akmal Ferdiyan, Reinard Primulando, Fiki Taufik Akbar +1
We study lepton-flavor-violating (LFV) decays of a heavy Higgs boson, , in the Type-III two-Higgs-doublet model by recasting the CMS search at TeV with…
Threshold-Sharp Conformal Scalar Stability on Carter Slabs and Black Hole Exteriors
Bobby Eka Gunara
We prove a threshold-sharp stability theory for the conformal scalar-curvature sector on zero-curvature Carter backgrounds. The main result is a fully closed bounded-slab theorem:…
Preliminary study on the impact of stress-energy tensor compared to scalar field in Nonminimal Derivative model
Ilham Prasetyo, Bobby Eka Gunara, Agus Suroso
In this article, we report the results of comparing the effect of using trace of stress-energy tensor versus real-valued scalar field in Nonminimal Derivative Coupling gravitation…
