Vainshtein Solutions Without Superluminal Modes
Gregory Gabadadze, Rampei Kimura, David Pirtskhalava
The Vainshtein mechanism suppresses the fifth force at astrophysical distances, while enabling it to compete with gravity at cosmological scales. Typically, Vainshtein solutions ex…
Inflation from Minkowski Space
David Pirtskhalava, Luca Santoni, Enrico Trincherini +1
We propose a class of scalar models that, once coupled to gravity, lead to cosmologies that smoothly and stably connect an inflationary quasi-de Sitter universe to a low, or even z…
decays to two pseudoscalars and a generalized rule
Benjamín Grinstein, David Pirtskhalava, David Stone +1
We perform an isospin analysis of decays to two pseudoscalars. The analysis extracts appropriate CKM and short distance loop factors to allow for comparison of non-perturbative…
Selfacceleration with Quasidilaton
Gregory Gabadadze, Rampei Kimura, David Pirtskhalava
Quasidilaton massive gravity is an extension of massive General Relativity to a theory with additional scale invariance and approximate internal Galilean symmetry. The theory has a…
Theoretical Constraints on Additional Higgs Bosons in Light of the 126 GeV Higgs
Benjamín Grinstein, Christopher W. Murphy, David Pirtskhalava +1
We present a sum rule for Higgs fields in general representations under that follows from the connection between the Higgs couplings and the mechanism that…
