Faster than light neutrinos still in the spotlight

Por: System Administrator  En: Jue 15 de Mar, 2012 22:47 -05  (978 Lecturas)
The ICARUS experiment in Gran Sasso Laboratory (where OPERA is also located) contradicts the results of his neighbor (they could not see any faster than light neutrino).

Sending the word "neutrino" with neutrinos

Por: System Administrator  En: Jue 15 de Mar, 2012 22:24 -05  (1364 Lecturas)

From The Economist(external link): The message, which read "neutrino", was transcribed into a string of "0s" and "1s" using the standard code employed in digital communications. The beam was then tweaked so that a pulse created using a full bunch of protons corresponded to a "1", while one with no protons signalled a "0". The pulses were separated by 2.2 seconds and the message was repeated in cycle for about two hours.

At the receiving end, each "1" translated into an average of 0.8 neutrino events registered in the detector; a "0", naturally, translated into none. This was enough to reconstruct the message accurately.

Daya Bay experiment just announced the measurement of one of the last parameter of the oscillation interpretation of neutrino experiments: $\theta_{13}$. See for example the discussion in Résonaances(external link).


$U_{13}^2=0.023\pm0.004$

Centre opens ICTP South American Institute for Fundamental Research
Instituto de Fisica Teorica (IFT-UNESP), the site of ICTP's new South American Institute for Fundamental Research ICTP has opened a regional branch in Sao Paulo, Brazil, to bring its unique blend of high-quality physics and mathematics education and high-level science meetings closer to scientists in South America.

The ICTP South American Institute for Fundamental Research is a regional centre for theoretical physics created in collaboration with the State University of Sao Paulo (UNESP) and the Sao Paulo Research Funding Agency (FAPESP). It is located on the campus of the Instituto de Fisica Teorica (IFT-UNESP).

Activities, which are modelled on those of ICTP, will begin in 2012 with international schools and workshops. The Institute also will have an active visitors' programme together with several postdoctoral and permanent research professor positions. Applications for these positions, as well as for scientific visits and proposals for 2013 activities, are available on the Institute's [Centre opens ICTP South American Institute for Fundamental Research
