TL;DR: It is found that the production of the h(b)(1P) and h (b)(2P) is not suppressed relative to theProduction of the Υ(1S), Υ (2S), and Γ(3S) and Υ-3S, and the states are produced in the reaction e(+)e(-)→h( b)(nP).
Abstract: We report the first observations of the spin-singlet bottomonium states h(b)(1P) and h(b)(2P). The states are produced in the reaction e(+)e(-) --> h(b)(nP)pi(+)pi(-) using a 121.4 fb(-1) data sample collected at energies near the Y(5S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. We determine M[h(b)(1P)] = (9898.2(-1.0-1.1)(+1.1+1.0)) MeV/c(2) and M[h(b)(2P)] = (10 259.8 +/- 0.6(-1.0)(+1.4)) MeV/c(2), which correspond to P-wave hyperfine splittings Delta M-HF = (+1.7 +/- 1.5) and (+0.5(-1.2)(+1.6)) MeV/c(2), respectively. The significances of the h(b)(1P) and h(b)(2P) are 5.5 sigma and 11.2 sigma, respectively. We find that the production of the h(b)(1P) and h(b)(2P) is not suppressed relative to the production of the Y(1S), Y(2S), and Y(3S).

TL;DR: The final fate of a massive star collapsing under the force of its own gravity is either a black hole or a naked singularity under a wide variety of physically reasonable circumstances within the framework of general theory of relativity.
Abstract: It is now known that when a massive star collapses under the force of its own gravity, the final fate of such a continual gravitational collapse will be either a black hole or a naked singularity under a wide variety of physically reasonable circumstances within the framework of general theory of relativity. The research of recent years has provided considerable clarity and insight on stellar collapse, black holes and the nature and structure of spacetime singularities. We discuss several of these developments here. There are also important fundamental questions that remain unanswered on the final fate of collapse of a massive matter cloud in gravitation theory, especially on naked singularities which are hypothetical astrophysical objects and on the nature of cosmic censorship hypothesis. These issues have key implications for our understanding on black hole physics today, its astrophysical applications, and for certain basic questions in cosmology and possible quantum theories of gravity. We consider these issues here and summarize recent results and current progress in these directions. The emerging astrophysical and observational perspectives and implications are dicussed, with particular reference to the properties of accretion discs around black holes and naked singularities, which may provide characteristic signatures and could help distinguish these objects.

TL;DR: This is the first measurement of inclusive W and Z boson production in proton-proton collisions at sqrt[s] = 8 TeV, and the measured values agree with next- to-next-to-leading-order QCD cross section calculations.

TL;DR: The significance of Planck length in a quantum gravity model is investigated by concentrating on the conformal degree of freedom as mentioned in this paper, which is a lower bound to physical proper length in any space-time.

TL;DR: In this article, the BPS and low energy non-BPS excitations of the D-string in terms of open strings that travel on the Dstring were examined, and the energy thresholds for exciting a long D string, for arbitrary winding number, were studied.
