TL;DR: In this paper, the problem of the Newtonian limit in nonlinear gravity models was revisited and two models with inverse powers of R = 0 were proposed, where R ≥ 0 and R ≥ 1, respectively.

TL;DR: Path integrals provide in many instances an elegant complementary description of quantum mechanics and also for the quantization of fields, which will be studied from a canonical point of view in Chapter ?? and following chapters.

TL;DR: In this article, the authors consider the possibility that ultra-high energy cosmic rays originate from the annihilation of superheavy dark matter and calculate the possible signature from annihilation in sub-galactic clumps of dark matter, and find that the signal from sub-clumps dominates and may explain the observed flux with a much smaller cross-section than if the super heavy dark matter is smoothly distributed.

TL;DR: The search for particle-like dark matter with meV-to-GeV masses has developed rapidly in the past few years as mentioned in this paper , and the science case for these searches, the recent progress, and the exciting upcoming opportunities.

TL;DR: It is well known that any scalar can be promoted to a Jordan-Brans-Dicke type scalar coupling to the Einstein-Hilbert term through a field dependent Weyl transformation of the metric as mentioned in this paper.
