Cosmic inflation driven by the vacuum energy associated with the $D$ term of a supersymmetric Abelian gauge group and a possible existence of long-range force mediated by an ultralight gauge boson ${Z}^{\ensuremath{'}}$ are two extreme examples of models based on extra $U(1)$ symmetries. Large vacuum energy sets the scale of inflation while the scales of long-range forces induced by anomaly free extra gauged $U(1)$ symmetries are constrained by neutrino oscillations, binary pulsar timings, and…

A closed clockwork theory: $\mathbb{Z}_2$ parity and more

: We develop a new class of clockwork theories with an augmented structure of the near-neighbour interactions along a one-dimensional closed chain. Such a topology leads to new and attractive

Probing light mediators in the radiative emission of neutrino pair

We propose a new possibility of using the coherently enhanced neutrino pair emission to probe light-mediator interactions between electron and neutrinos. With typical momentum transfer at the atomic

Constraints on long range force from perihelion precession of planets in a gauged L e − L μ,τ scenario

The standard model leptons can be gauged in an anomaly free way by three possible gauge symmetries namely L e − L μ , L e − L τ , and L μ − L τ . Of these, L e − L μ and L e − L τ forces can mediate

Constraints on long range force from perihelion precession of planets in a gauged $$L_e-L_{\mu ,\tau }$$ scenario

The standard model particles can be gauged in an anomaly free way by three possible gauge symmetries namely ${L_e-L_\mu}$, ${L_e-L_\tau}$, and ${L_\mu-L_\tau}$. Of these, ${L_e-L_\mu}$ and

Low-scale D -term inflation and the relaxion mechanism

We present a dynamical cosmological solution that simultaneously accounts for the early inflationary stage of the Universe and solves the supersymmetric little hierarchy problem via the relaxion

Inflation from high-scale supersymmetry breaking

Supersymmetry breaking close to the scale of grand unification can explain cosmic inflation. As we demonstrate in this paper, this can be achieved in strongly coupled supersymmetric gauge theories,

Unified model of D-term inflation

Hybrid inflation, driven by a Fayet-Iliopoulos (FI) D term, is an intriguing inflationary model. In its usual formulation, it however suffers from several shortcomings. These pertain to the origin of

Large field excursions and approximate discrete symmetries from a clockwork axion

We present a renormalizable theory of scalars in which the low-energy effective theory contains a pseudo-Goldstone boson with a compact field space of 2 pi F and an approximate discrete shift

Horizon ratio bound for inflationary fluctuations.

We demonstrate that the gravity wave background amplitude implies a robust upper bound on the wavelength-to-horizon ratio at the end of inflation: lambda/H(-1) less than or approximately equal e(60),
