    F(750), We Miss You, as Bound State of 6 Top and 6 Anti top

    Full text link
    We collect and estimate support for our long speculated "multiple point principle" saying that there should be several vacua all having (compared to the scales of high energy physics) very low energy densities. In pure Standard Model we suggest there being three by "multiple point principle" low energy density vacua, "present", "condensate" and "high field" vacuum. We fit the mass of the in our picture since long speculated bound state of six top and six anti top quarks in three quite {\em independent ways} and get remarkably within our crude accuracy the {\em same} mass in all three fits! The new point of the present article is to estimate the bound state mass in what we could call a bag model estimation. The two other fits, which we review, obtain the mass of the bound state by fitting to the multiple point principle prediction of degenerate vacua. Our remarkable agreement of our three mass-fits can be interpreted to mean, that we have calculated at the end the energy densities of the two extra speculated vacua and found that they are indeed very small!. Unfortunately the recently much discussed statistical fluctuation peak F(750) has now been revealed to be just a fluctuation, very accidentally matches our fitted mass of the bound state remarkably well with the mass of this fluctuation 750 GeV.Comment: minor corrections in calculation and commas and a few references added. arXiv admin note: text overlap with arXiv:1607.07907, adding few citation

    Intraday liquidity management: a tale of games banks play

    Over the last few decades, most central banks, concerned about settlement risks inherent in payment netting systems, have implemented real-time gross settlement (RTGS) systems. Although RTGS systems can significantly reduce settlement risk, they require greater liquidity to smooth nonsynchronized payment flows. Thus, central banks typically provide intraday credit to member banks, either as collateralized credit or priced credit. Because intraday credit is costly for banks, how intraday liquidity is managed has become a competitive parameter in commercial banking and a policy concern of central banks. This article uses a game-theoretical framework to analyze the intraday liquidity management behavior of banks in an RTGS setting. The games played by banks depend on the intraday credit policy of the central bank and encompass two well-known paradigms in game theory: "the prisoner's dilemma" and "the stag hunt." The former strategy arises in a collateralized credit regime, where banks have an incentive to delay payments if intraday credit is expensive, an outcome that is socially inefficient. The latter strategy occurs in a priced credit regime, where postponement of payments can be socially efficient under certain circumstances. The author also discusses how several extensions of the framework affect the results, such as settlement risk, incomplete information, heterogeneity, and repeated play.Payment systems ; Banks and banking, Central ; Bank liquidity ; Game theory ; Credit

    Formulation of Complex Action Theory

    Full text link
    We formulate a complex action theory which includes operators of coordinate and momentum q^\hat{q} and p^\hat{p} being replaced with non-hermitian operators q^new\hat{q}_{new} and p^new\hat{p}_{new}, and their eigenstates m<newq{}_m <_{new} q | and m<newp{}_m <_{new} p | with complex eigenvalues qq and pp. Introducing a philosophy of keeping the analyticity in path integration variables, we define a modified set of complex conjugate, real and imaginary parts, hermitian conjugates and bras, and explicitly construct q^new\hat{q}_{new}, p^new\hat{p}_{new}, m<newq{}_m <_{new} q | and m<newp{}_m <_{new} p | by formally squeezing coherent states. We also pose a theorem on the relation between functions on the phase space and the corresponding operators. Only in our formalism can we describe a complex action theory or a real action theory with complex saddle points in the tunneling effect etc. in terms of bras and kets in the functional integral. Furthermore, in a system with a non-hermitian diagonalizable bounded Hamiltonian, we show that the mechanism to obtain a hermitian Hamiltonian after a long time development proposed in our letter works also in the complex coordinate formalism. If the hermitian Hamiltonian is given in a local form, a conserved probability current density can be constructed with two kinds of wave functions.Comment: 29 pages, 2 figures, references added, presentation improved, typos corrected. (v5)The definition of q^new\hat{q}_{new} and p^new\hat{p}_{new} are corrected by replacing them with their hermitian conjugates. The errors and typos mentioned in the errata of PTP are corrected. arXiv admin note: substantial text overlap with arXiv:1009.044

    Model-based development and testing of advertising messages – A comparative study of two campaign proposals based on the Meccas model and a conventional approach,

    1. Traditionally the development of advertising messages has been based on “creative independence”, sometimes catalysed by inductively generated empirical data. Due to the recent intensified focus on advertising effectiveness, this state of affair is now beginning to change. 2. Implementing theoretically valid and comprehensible guidelines for message development potentially enhances the effects of advertising messages and improves the possibility of measuring such effects. Moreover, such guidelines also have potential implications for the managerial communication processes (client-agency and intra-agency) involved in the development of advertising messages. 3. The purpose of the study described in this paper is to compare the development and effects of two campaign proposals, with the common aim of increasing the consumption of apples among young Danes (18 to 35 years of age). One of the proposals is the result of an inductive-creative process, while the other is based on the MECCAS model, ie, means-end based data collection employing the laddering method and subsequent use of the guidelines for message development formulated in MECCAS. 4. The comparison involved target group communication effects as well as the efficiency of the managerial communication taking place in the message development process. The target group communication was assessed by pretesting the two campaign proposals (n=500). Linear structural Elam (Elaboration likelihood) models were estimated for both proposals. The managerial communication was studied by interviews with the advertising agency and client staff involved. The project is a joint venture of the Association of Danish Fruit Growers, Odense, Denmark, and the MAPP Centre, and is financed by EU funds. The advertising agency involved is Midtmarketing, Ikast, Denmark. 5. The main results of the managerial study was that the implementation of the MECCAS guidelines for message development led to better agency-client communication, which resulted in an improved common understanding of the objective of the campaign. The pretest showed that the MECCAS-based message compared to the conventionally developed message was perceived as more focused by the target group, stimulated central processing better, and was more effective in terms of self-reported buying intention.Concept and design in advertising; Advertising campaigns; Effects of advertising

    Seeking a Game in which the standard model Group shall Win

    Full text link
    It is attempted to construct a group-dependent quantity that could be used to single out the Standard Model group S(U(2) x U(3)) as being the "winner" by this quantity being the biggest possible for just the Standard Model group. The suggested quantity is first of all based on the inverse quadratic Cassimir for the fundamental or better smallest faithful representation in a notation in which the adjoint representation quadratic Cassimir is normalized to unity. Then a further correction is added to help the wanted Standard Model group to win and the rule comes even to involve the Abelian group U(1) to be multiplied into the group to get this correction be allowed. The scheme is suggestively explained to have some physical interpretation(s). By some appropriate proceedure for extending the group dependent quantity to groups that are not simple we find a way to make the Standard Model Group the absolute "winner". Thus we provide an indication for what could be the reason for the Standard Model Group having been chosen to be the realized one by Nature.Comment: already publiched in 2011 in Bled Conference proceedings "What comes beyond the Stadard Models

    The Cheshire Cat Principle from Holography

    Full text link
    The Cheshire cat principle states that hadronic observables at low energy do not distinguish between hard (quark) or soft (meson) constituents. As a result, the delineation between hard/soft (bag radius) is like the Cheshire cat smile in Alice in wonderland. This principle reemerges from current holographic descriptions of chiral baryons whereby the smile appears in the holographic direction. We illustrate this point for the baryonic form factor.Comment: 11 pages, 2 figure
