Lepton Number Conservation, Long-lived Quarks and Superweak Bileptonic Decays

In the upcoming LHC Run 2, at $\sqrt{s} \sim13$ TeV, it is suggested to seek unusually charged ($Q= -4/3$ and $+5/3$) quarks with mass $M_Q \sim 3$ TeV which carry lepton number ($L = +2$ and $-2$ respectively) and decay superweakly to a bilepton $Y$ with mass $M_Y\sim2.5$ TeV and a usual quark. These long-lived decays will have displaced decay vertices and produce a striking final state in $pp$ which contains two separated jets together with two pairs of correlated like-sign charged leptons. Such a process was inaccessible energetically in LHC Run 1 with $\sqrt{s} \sim8$ TeV. The simplest theoretical explanation is the 331-model which has new physics necessarily below $4$ TeV and which explains the existence of three families by anomaly cancellation.Comment: 7 pages LaTe

Quiver Approach to Massive Gauge Bosons Beyond the Standard Model

We address the question of the possible existence of massive gauge bosons beyond the $W^{\pm}$ and $Z^{0}$ of the standard model. Our intuitive and aesthetic approach is based on quiver theory. Examples thereof arise, for example, from compactification of the type IIB superstring on $AdS_5 \times S_5/ Z_n$ orbifolds. We explore the quiver theory framework more generally than string theory. The practical question is what gauge bosons to look for at the upgraded LHC, in terms of color and electric charge, and of their couplings to quarks and leptons. Axigluons and bileptons are favored.Comment: 6 pages, 0 figure

Possible solution of dark matter, the solution of dark energy and Gell-Mann as great theoretician

This talk discusses the formation of primordial intermediate-mass black holes, in a double-inflationary theory, of sufficient abundance possibly to provide all of the cosmological dark matter. There follows my, hopefully convincing, explanation of the dark energy problem, based on the observation that the visible universe is well approximated by a black hole. Finally, I discuss that Gell-Mann is among the five greatest theoreticians of the twentieth century.Comment: References update

Rhetoric and Reality The Obamacare Evaluation Report: Access to Care and the Physician Shortage

President Barack Obama's first term was defined by the battle over, and the passage of, the Patient Protection and Affordable Care Act, the landmark health-reform legislation known popularly as Obamacare. Along the way, Obama, the law's supporters, and independent analysts such as the Congressional Budget Office (CBO) made specific claims or projections about how the law would affect consumers, patients, and businesses.Now, three years after Obamacare's passage, many key provisions of the legislation are beginning to be implemented. Whether implementation succeeds or fails will be strongly influenced by the reactions of states, providers, insurers, businesses, and consumers to the law's provisions and to the thousands of pages of new health-care regulations.Rhetoric and Reality is a project of the Manhattan Institute's Center for Medical Progress that is designed to offer an ongoing, objective, and accessible perspective on the law's performance in light of key claims or projections made about it. Our project will examine the law's effect on Americans in five overarching areas: health-care costs, insurance coverage, employment, access to care, and consumer-driven health plans. Additional topics may be added.Each evaluation will be based on the best available data and will be revised as new or more authoritative data become available
