"Leptons interact only with photons, and with the intermediate bosons that presumably mediate weak interactions. What could be more natural than to unite these spin-one bosons into a multiplet of gauge fields ? Standing in the way of this synthesis are the obvious differences in the masses of the photon and the intermediate (boson), and in their couplings. We might hope to understand these differences by imagining that the symmetries relating the weak and electromagnetic interactions are exact symmetries of the Lagrangian but are broken by the vacuum".

This is going to be a short post where I confess my recent troubles with keeping everything going on at full speed in my life, while the workload constantly grows.

I believe it is a temporary problem -I have experienced the same situation in the past- but I feel swamped by a few things that have piled up. So today, rather than reading on a new physics result or a new article on the arxiv, you are going to find here a list of the things I am not attending in order to write this short post. In random order:

1. I have a undergraduate thesis to correct.
2. I also need to write a reference letter for him, by next Sunday.
3. There is a 100 pages paper in internal review by CDF and I am a member of the review committee.
