[The title of this article comes from a T-shirt with ten advices on what to do when everything else fails]

It has always surprised me to realize how confident we physicists are of the good faith of our colleagues. We may argue endlessly over one graph or result, getting to the point of publically casting doubts on the dexterity or intelligence of our peers (yes, I've seen that), but we never seem to doubt -privately or otherwise- their scientific integrity.
"The cusp in the dark matter distribution required to explain the recently found excess in the gamma-ray spectrum at energies of 130 GeV in terms of the dark matter annihilations cannot survive the tidal forces if it is offset by 1.5° from the Galactic center as suggested by observations."

"Oh Wind, if Winter comes, can Spring be far behind ?"

Good old Shelley inspired me to start today's article with the above verse, taken from his magnificent "Ode to the West Wind". With the weather we are experiencing these days in Geneva and northern Italy, I found it a relieving thought...

So, winter conferences are over, and summer ones are still far away. This is therefore a nice moment to try an assessment on the quality of the results that the two competing CERN experiments have produced on the study of the Higgs boson. Why ? Because we are not going to have to change our conclusions in a short time scale caused by a result about to be published.

How to compare the results
The results of a third-party investigation of Rossi's E-CAT reactor have appeared on the Cornell arxiv, and the conclusions of the tests are at the very least startling:
"New Physics can appear at any moment but it is now conceivable that no new physics will show up at the LHC"

Guido Altarelli, LHC Nobel Symposium, May 15th 2013

It is funny reading the above quote if you are one who "conceived" that the LHC could find no new physics 7 years ago, as demonstrated by where I put my money...
Finally the decay of Higgs bosons to b-quark pairs is emerging from LHC data, too.
