Light Bending in Models with a Generic Scalar Field
Dongjin Chway
We study the deflection and time delay of light by the Sun in general scalar extensions of the Standard Model which may violate the equivalence principle. Despite the presence of t…

The dS swampland conjecture with the electroweak symmetry and QCD chiral symmetry breaking
Kiwoon Choi, Dongjin Chway, Chang Sub Shin
The dS swampland conjecture , where is presumed to be a positive constant of order unity, implies that the dark energy density of our Universe can not be a…
