ICARUS: Neutrinos Travel At Light Speed. Period.

Little less than one year ago the world of fundamental physics was shaken by the bold claim of the OPERA collaboration, which produced a measurement of the time of flight of neutrinos traveling underground from Geneva to the Gran Sasso mine in central Ital ...

A Fifth Force to explain the Handedness of the Weak Force

The weak force is the most mysterious force in the standard model, it is the only force thatisn't long range, thanks to the Higgs mechanism, the weak forces carriers gain a mass can only travel a very short distance before there borrowed energy runs o ...

The Plot Of The Week- Z' Not Here

Perhaps a bit too simple, but certainly appealing. Extensions of the Standard Model which imply the existence of a new U(1) gauge group to complement the SU(2)xU(1) structure of electroweak interactions have been put forth in a number of slightly different ...

Quantum Graphity And Early Universe Formation: Big Bang Or Big Chill?

The start of the Universe may have been more like water freezing into ice than the popular conception of a Big Bang, say theoretical physicists from the University of Melbourne and RMIT University. They have a new hypothesis (conjecture?) which suggests th ...

Russians find new Particle, E(38) at 38 MeV

Russians at the JINR Nuclotron believe they have found a new particle, the E(38), as reported in this paper at ArXiv. The particle interacts with quarks and gluons only and appears in collisions on nucleii. It decays to two photons, and its width (inverse ...

My Take On The Would-Be Particle At 38 MeV

Everybody seems to be talking about this new would-be particle, allegedly observed in diphoton decays in this paper by Kh. Abraamyan et al. at JINR, and consistent with an earlier claim of two physicists (van Beveren and Rupp) who had considered several di ...

The Buddha, Topoi, And Quantum Gravity

Anything is either true, Or not true, Or both true and not true, Or neither true nor not true; This is the Buddha's teaching.--Nagarjuna (second century Buddhist monk and philosopher), the Mulamadhyamakakarika, Chapter XVIII, verse 8 (Note: there are ...

An experiment to detect currents due to an Axial Force

In last weeks post,I introduced the Axial force, a force interacting between neutrinos, left handed neutrino repel other left handed neutrino while attracting right handed anti-neutrinos or indeed right handed neutrino (if there where any). We may follow i ...

The Plot Of The Week- New SUSY Limits From ATLAS

A new ATLAS search for supersymmetric signatures in 2011 LHC data has appeared last week in the arxiv. The result? No hint of a signal, not even for ready money. So if you are on a hurry, you can just have a glance at the graph below, which summarizes the ...

CMS Week in Lisbon

Large collaborations of physicists have a consolidated habit of meeting three or four times per year for a full week of discussions and talks. This has multiple purposes, one of them being the possibility to bring together members who live and work off-sit ...
