Hi Daryl,
Thanks for posting your comments.
Indeed, I take issue with the fact that the claim of the CMS collaboration goes against elementary logic: it's a fallacy. It doesn't matter that the Higgs is the only contender at this moment: it remains a fallacy. You cannot say: these are traces of a Higgs boson, therefore the Higgs boson exists. Then you're assuming what has to be proven (it's a circular reasoning).
You are correct in your statement that I haven't said anything about what else that observed peak could have been. My essay is purely critical: I only question the conclusion of the CMS collaboration that the Higgs boson has been observed. So to provide somewhat of an answer to your question, I would say: the Higgs boson is currently the best possible explanation for the observed peak(s). But then we're talking about an 'explanation', not about an 'observation'. Big difference. If it's the best possible explanation, then it still might be the case that we find a better explanation at a later time. But if it's an observation, then that's final: then the Higgs boson exists, period. Then there is no other explanation for the observed peak(s). And in my opinion, they cannot make that claim.
Best regards,
