LOG#172. Higgscelebration: 3 years of a Higgs-like boson!

In 2012, July 4th…We had the Higgsdependence day! A SM Higgs-like resonance was discovered at the LHC and was announced to the world. Today, we celebrate this discovery of the Higgs-like thing or particle almost 3 years ago. So let … Continue reading

LOG#139. The Higgs and beyond.

The discovery of the Higgs boson in 2012 rises new questions: 1º) Is it the SM Higgs or an impostor? It seems like a SM Higgs but…We don’t know yet for sure. 2º) Is it the ONLY Higgs-like particle or … Continue reading

LOG#137. Unparticles.

One of the most interesting ideas of the last years between theoretical particle physicists came from conformal field theories (CFT). In their last incarnation, Georgi’s unparticles. What is an unparticle? Georgi, a very known and respected theoretical physicist, speculates about … Continue reading

LOG#122. Basic Neutrinology(VII).

The observed mass and mixing both in the neutrino and quark cases could be evidence for some interfamily hierarchy hinting that the lepton and quark sectors were, indeed, a result of the existence of a new quantum number related to … Continue reading

LOG#118. Basic Neutrinology(III).

Mass terms Phenomenologically, lagrangian mass terms can be understood as terms describing “transitions” between right (R) and left (L) handed states in the electroweak sector. For a given minimal, Lorentz invariant set of 4 fields (), we have the components … Continue reading

LOG#117. Basic Neutrinology(II).

The current Standard Model of elementary particles and interactions supposes the existence of 3 neutrino species or flavors. They are neutral, upper components of “doublets” with respect to the group, the weak interaction group after the electroweak symmetry breaking, and … Continue reading

LOG#116. Basic Neutrinology(I).

This new post ignites a new thread. Subject: the Science of Neutrinos. Something I usually call Neutrinology.   I am sure you will enjoy it, since I will keep it elementary (even if I discuss some more advanced topics at some … Continue reading

LOG#047. The Askaryan effect.

I discussed and reviewed the important Cherenkov effect and radiation in the previous post, here: http://www.thespectrumofriemannium.com/?p=3276 Today we are going to study a relatively new effect ( new experimentally speaking, because it was first detected when I was an undergraduate … Continue reading
