Search for Effect of Influence from Future in Large Hadron Collider
We propose an experiment which consists of drawing a card and using it to
decide restrictions on the running of Large Hadron Collider (LHC for short) at
CERN, such as luminosity, and beam energy. There may potentially occur total
shut down. The purpose of such an experiment is to search for influence from
the future, that is, backward causation. Since LHC will produce particles of a
mathematically new type of fundamental scalars, i.e., the Higgs particles,
there is potentially a chance to find unseen effects, such as on influence
going from future to past, which we suggest in the present paper.Comment: 18pp, comments added, change of title and corrections of main text;

Dimension Four Wins the Same Game as the Standard Model Group
In a previous article Don Bennett and I looked for,found and proposed a game
in which the Standard Model group S(U(2)XU(3)) gets singled out as the
"winner". Here I propose to extend this "game" to construct a corresponding
game between different potential dimensions for space time. The idea is to
formulate how the same competition as the one between the potential gauge
groups would run out, if restricted to the potential Lorentz or Poincare groups
achievable for different dimensions of space time d. The remarkable point is
that it is the experimental dimension of space time 4 which wins. So the same
function defined over Lie groups seems to single out both the gauge group and
the space time dimension in nature. This seems a rather strange coincidence
unless there is really some similar physics behind.Comment: After introducing some more review o the previous article the
historical stuff was moved into an appendi
Initial Condition Model from Imaginary Part of Action and the Information Loss
We review slightly a work by Horowitz and Maldecena solving the information
loss problem for black holes by having inside the blackhole - near to the
singularity - a boundary condition, as e.g the no boundary proposal by Hartle
and Hawking. Here we propose to make this boundary condition come out of our
imaginary action model (together with Masao Ninomiya). This model naturally
begins effectively to set up boundaries - whether it be in future or past! -
especially strongly whenever we reach to high energy physics regimes, such as
near the black hole singularity, or in Higgs producing machines as LHC or SSC.
In such cases one can say our model predicts miracles. The point is that you
may say that the information loss problem, unless you solve it in other ways,
call for such a violation of time causality as in our imaginary action model!Comment: Proceedings to ``Black Holes in General Relativity and String

On the distribution of stellar-sized black hole spins
Black hole spin will have a large impact on searches for gravitational waves
with advanced detectors. While only a few stellar mass black hole spins have
been measured using X-ray techniques, gravitational wave detectors have the
capacity to greatly increase the statistics of black hole spin measurements. We
show what we might learn from these measurements and how the black hole spin
values are influenced by their formation channels.Comment: 4 pages, 2 figures, pre-GW150914 detection, refereed and accepted

String from Veneziano model
This article is about my memories from the discovery that the Veneziano model
describes in fact interacting strings. I came to the understanding of that the
dual or Veneziano model is really a model of strings independently of L.
Susskind and Y. Nambu. A characteristic feature of my approach was that I used
thinking of very high order "fishnet" or planar Feynman diagrams as the way of
at first describing the development of the strings. A chain of constituents
leads to planar diagrams dominating when only neighbours on the chain interact
significantly. The article also mentions the works of Ziro Koba and mine about
extending the Veneziano model first to five external particles - as Bardakci
and Ruegg, Chan Tsou, and Goebel and Sakita also did - and subsequently to an
arbitrary number n of external mesons.Comment: 10 pages, contribution to Conference "The Birth of String Theory" by

Test for cointegration rank in general vector autoregressions
Johansen derived the asymptotic theory for his cointegration rank test statisic for a vector autoregression where the parameters are restricted so the process is integrated of order one. It is investigated to what extent these parameter restrictions are binding. The eigenvalues of Johansen’s eigenvalue problem are shown to have the same consistency rates accross the parameter space. The test statistic is shown to have the usual asymptotic distribution as long as the possibilities of additional unit roots and of singular explosiveness are ruled out. To prove the results the convergence of stochastic integrals with respect to singular explosive processes is considered.
