El Grupo de Fenomenología de Interacciones Fundamentales, es un Grupo de Investigación de la Universidad de Antioquia

que enfoca su investigación en física más allá del modelo estándar (Espera a que LaTeX sea procesado..., i.e, $\cal{L}=i\bar{\psi}\gamma^\mu\partial_\mu\psi$)

Visita de Stephen Hawking a la seríe de televisión: 'The Big Bang Theory'

Por: System Administrator En: Lun 09 de Abr, 2012 05:10 GMT (59 Lecturas)

El físico y divulgador científico Stephen Hawking se convirtió el pasado jueves en el protagonista de la televisión estadounidense. Todo por su aparición en un capítulo de la serie de CBS The Big Bang Theory, en la que Hawking se interpretó a sí mismo, con 13 millones de espectadores

Ruptura espontánea de simetría en grafeno molecular

Por: System Administrator En: Sáb 31 de Mar, 2012 06:15 GMT (92 Lecturas)

Desde la Ciencia de la Mula

Francis: omes y sus colegas han estudiado la transición de un “grafeno molecular” a una disposición periódica que se conoce como estructura de Kekulé; en esta transición los fermiones de Dirac sin masa adquieren masa. La teoría predice que esta transición debería ir acompañada de la aparición de un campo gauge; estos físicos han observado que los fermiones tras adquirir masa se comportan como si estuvieran en un campo magnético. La aparición y desaparición de un campo magnético “aparente” (que los autores llaman “campo pseudomagnético”) ...

Faster than light neutrinos still in the spotlight

Por: System Administrator En: Vie 16 de Mar, 2012 03:47 GMT (84 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: Vie 16 de Mar, 2012 03:24 GMT (61 Lecturas)

From The Economist

: 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

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

Historial

Search Help

Non Advanced Search or Natural Search

The documents are returned sorted on relevance depending on order, proximity, frequency of terms.

Advanced Search or Boolean Search

Default search behavior

By default, all search terms are optional. It behaves like an OR logic. Objects that contain the more terms are rated higher in the results and will appear first in their type. For example, wiki forum will find:

objects that include both terms
objects that include the term wiki
objects that include the term forum

Requiring terms

Add a plus sign ( + ) before a term to indicate that the term must appear in results. Example: +wiki forum will find objects containing at least wiki. Objects with both terms and many occurences of the terms will appear first.

Excluding terms

Add a minus sign ( - ) before a term to indicate that the term must not appear in the results. To reduce a term's value without completely excluding it, use a tilde. Example: -wiki forum will find objects that do not contain wiki but contain forum

Grouping terms

Use parenthesis ( ) to group terms into subexpressions. Example: +wiki +(forum blog) will find objects that contain wiki and forum or that contain wiki and blog in any order.

Finding phrases

Use double quotes ( " " ) around a phrase to find terms in the exact order, exactly as typed. Example: "Alex Bell" will not find Bell Alex or Alex G. Bell.

Using wildcards

Add an asterisk ( * ) after a term to find objects that include the root word. For example, run* will find:

objects that include the term run
objects that include the term runner
objects that include the term running

Reducing a term's value

Add a tilde ( ~ ) before a term to reduce its value indicate to the ranking of the results. Objects that contain the term will appear lower than other objects (unlike the minus sign which will completely exclude a term). Example: +wiki ~forum will rate an object with only wiki higher that an object with wiki and forum.

Changing relevance value

Add a less than ( < ) or greater than ( > ) sign before a term to change the term's contribution to the overall relevance value assigned to a object. Example: +wiki +(>forum < blog) will find objects that contain wiki and forum or wiki and blog in any order. wiki forum will be rated higher.
