I think it is due time that I point out a few interesting articles that have appeared in the past couple of months in the blog of the AMVA4NewPhysics network
, a consortium of 16 among universities, research institutes, and industries that has the goal of studying Higgs physics and new Physics with the LHC, using advanced statistical learning methods.
On March 3rd and 4th the AMVA4NewPhysics network
met in Venice, in the beautiful venue of Ca' Sagredo. Ca' Sagredo is a 500-year-old palace on the Canal Grande, home of the Sagredo family and in the 600s of Giambattista Sagredo, who hosted many times Galileo Galilei there. As for the AMVA4NewPhysics network, it is a "Innovative Training Network" of 16 research institutes, universities and industries that have joined forces to train young scientists in particle physics and the development of advanced multivariate-analysis tools.
Majorana or Dirac Neutrino Masses?
Small finite Majorana masses assume very heavy mass scale symmetry, considered in mainstream theories, but the predicted values of light neutrino masses from the necessary see-saw mechanism are uncertain.
How many phenomenological papers discussing the 750 GeV diphoton resonance have you read since December 15th 2015 ? I believe that having read none of them, or ten, does not make a big difference - you missed most of them anyways. In fact, I think the count has gone past 200 by now.
There is nothing so compelling as a story about falling down,
recovering your footing, and then charging over the goal line completely
redeemed … unless it is two such stories. The Denver Broncos’ Super Bowl 50
victory and the laser interferometer gravitational-wave observatory’s (LIGO’s)
detection of gravity waves offer parallel examples. What, football and physics?
Yep. I watched the big game on TV, like tens of millions of others. But as a
technical consultant to LIGO, I had a Goodyear blimp’s view of their gridiron
when the collaboration fumbled its funding, recovered its mojo, and then sprinted to
victory by observing gravitational radiation generated more than a billion
One of the things I like the most when I do data analysis is to use "pure thought" to predict in advance the features of a probability density function of some observable quantity from the physical process I am studying. By doing that, one can try one's hand at demonstrating one's understanding of the details of the physics at play.
In this research we derived absolute neutrino masses by geometric interpretation of the Standard Model hierarchies. Numerous confirmations may indicate that, besides the problem of Higgs sector many external parameters, the SM is a complete low energy particle interaction theory not crying for new physics. But there are serious problems with understanding flavor in SM phenomenology. Firstly, equal number ‘3’ of SM particle generations coincide with the dimension number of outer euclidean 3-space and secondly, the factual SM particle mass and mixing hierarchies at leading approximation appear solutions of the ‘Metric’ equation for unit vector direction angles in euclidean 3-space geometry.
I (T.D.) am very happy to host here today a guest post by Daniel Hoak, a member of the LIGO collaboration, who participated in the discovery of gravitational waves that made headlines one week ago in the world media. Daniel earned his PhD in 2015 with the LIGO collaboration, and is currently working at the Virgo detector outside of Pisa. Daniel's picture is on the left.
Yesterday and today I have been spending time in Rome together with 600 Italian colleagues, at a symposium named "What Next". The idea is to discuss what should be the strategy of the institute to participate and support basic research in fundamental physics in the next few decades.
The format of the event is of short summary talks by ten "working groups" that examined different macro-areas: Precision SM Physics, Cosmic Ray Physics, Neutrino Physics, Flavour Physics, Gravitational Waves, Beyond the SM Physics, New Technologies, Fundamental Physics, and Dark Matter (I might have forgotten one). To each summary, delivered by two or three leaders of each working group, follows an open discussion that is allotted at least as much time as the presentations.
Information is not destroyed but it is even more scrambled up than anyone thought by black holes. I have used the framework of relativization, to compute the temperature of the proposed firewalls. It would be about 1.410 septillion Kelvin. Relativization which has been developed in open peer reviewed literature and conference presentation in to a comprehensive theory combining General Relativity with Quantum Field Theory. Black holes shred information, then burn it in a furnace hotter than millions of Suns.
