Today at CERN a workshop started on the physics of the High-Luminosity and High-Energy phases of Large Hadron Collider operations. This is a three-days event meant at preparing the ground for the decision on which, among several possible scenarios that have been pictured for the future of particle physics in Europe, will be the one on which the European Community will invest in the next few decades. The so-called "European Strategy for particle physics" will be decided in a couple of years, but getting the hard data on which to base that crucial decision is today's job.
Yesterday, October 20, was the international day of Statistics
. I took inspiration from it to select a clip from chapter 7 of my book "Anomaly! Collider physics and the quest for new phenomena at Fermilab"
which attempts to explain how physicists use the concept of statistical significance to give a quantitative meaning to their measurements of new effects. I hope you will enjoy it....
The Theory of Everything may be a mathematically simple model which is rich in implications and more difficult in concepts than calculations. The model I have just published as a candidate theory of everything is just such a model. String theory on the other hand is simple in concept but difficult in calculations. The concept of my model is that we treat all energy the same way. This is a MASSIVE oversimplification. All the scientific details for any experts that have questions are in the latest paper and the references to it.
Like many others, I listened to yesterday's (10/16/17) press release at the NSF without a special prior insight in the physics of neutron star mergers, or in the details of the measurements we can extract from the many observations that the detected event made possible. My knowledge of astrophysics is quite incomplete and piecemeal, so in some respects I could be considered a "layman" listening to a science outreach seminar.
Yet, of course, as a physicist I have a good basic understanding of the processes at the heart of the radiation emissions that took place two hundred million years ago in that faint, otherwise unconspicuous galaxy in Hydra.
At 10:00 AM this morning, my smartphone alerted me that in two months I will have to deliver a thorough review on the physics of boson pairs - a 50 page thing which does not yet even exist in the world of ideas. So I have better start planning carefully my time in the next 60 days, to find at least two clean weeks where I may cram in the required concentration. That will be the hard part!
Clamps are miniature
equivalents to the gravitational shock fronts caused by colliding black holes
that currently reach the press because very sensitive measuring equipment such
as LIGO can detect these fronts when they pass the
sensor. During travel, these fronts keep their shape, but the height
diminishes as 1/r as a function of the distance r to the trigger location. The
result is temporary, and the front integrates into the Green’s function of the
vibrating field. Thus, the spherical shock front deforms its carrier. Having
mass is synonym to having the capability to
deform its carrier. That vibrating field is our living space. Where a huge explosion triggers the front that passed
the LIGO sensor, are clamps triggered by a point-like artifact.
The top quark is the heaviest known matter corpuscle we consider elementary. Elementary is an overloaded word in English, so I need to explain what it means in the context of subatomic particles. If we grab a dictionary we get several possibilities, like e.g.- elementary: pertaining to or dealing with elements, rudiments, or first principles
- elementary: of the nature of an ultimate constituent; uncompounded
- elementary: not decomposable into elements or other primary constituents
- elementary: simple
Physical reality must be
Two and a
half centuries ago, scientist discovered solutions of the wave equation that
represent dark quanta.
Another chapter in the saga of the search for the elusive, but dominant, decay mode of the Higgs boson has been reported by the CMS collaboration last month
. This is one of those specific sub-fields of research where a hard competition arises on the answer to a relatively minor scientific question. That the Higgs boson couples to b-quarks is indirectly already well demonstrated by a number of other measurements - its coupling to (third generation) quarks being demonstrated by its production rate, for example. Yet, being the first ones to "observe" the H->bb decay is a coveted goal.
