What's the relationship between weakly hypercharged bosons and Higgs bosons? In this video, Leonard Susskind does a good job trying to explain succinctly the Higgs field and exactly how it gives elementary fermions mass, except for one point he seems to skip a few things. The weak hypercharge is endearingly called 'zilch' (0:46:00). He goes on to explain how (e.g.) an accelerating electron (or other zilch-charged particle) can emit a $Z$ boson. He then postulates (0:48:16) the existence of a field (none other than a 'ziggs boson condensate'), which (in a similar manner to a uniform electric field giving electric dipoles a potential energy - and therefore an extra mass - that depends on their orientation) gives fermions mass by the Dirac mechanism (explained earlier in the video). He adds how the ('zilch'-less) $Z$ boson also interacts with the 'ziggs' field to intermittently acquire 'zilch' (and becoming itself a 'ziggs'), and lose 'zilch', thereby acquiring mass as well.
At that point, he jumps to the Higgs boson without apparently any connection to the mechanism just explained (he employs different names for the fields). He explains that the Higgs boson is a particular excitation mode of the Higgs field, but what is then the (general) 'ziggs' boson? Are Higgs and ziggs actually the same? The $Z$ boson has been known experimentally for decades, what about its weakly hypercharged product? Does the Higgs boson actually have nothing to do with the Higgs phenomenon, being merely a consequence of the theory that was begging to be discovered experimentally?

If there was only a massive $Z$ boson, and nothing else, then this 'ziggs' mechanism would be sufficient and the slightly more complicated 'Higgs' mechanism would not be required. I would look at the 'ziggs' as what the 'Higgs' would look like in this scenario.

I presume by 'hypercharged product' you mean the charged $W^+$ and $W^-$ bosons. These are not products of the $Z$ boson, instead they are all a part of the same family of particles. Well its actually a bit more complicated than that... let's start from the top. The Higgs mechanism 'starts' with four massless bosons ($B^0$,$W^0$,$W^1$,$W^2$), which after some interacting with the Higgs field, will produce three massive bosons ($Z$,$W^+$,$W^-$) and one massless boson (which is the photon, $\gamma$). 
As there are four original bosons, without going into the heavier details, this means that the Higgs-field should be constructed from four components (or degrees of freedom). After interaction with the four components of the field, the four original bosons acquire a mass. However - as mentioned earlier - the photon is massless. In order to add this condition into our theory, we mix two of the original four bosons (the $B^0$ and $W^0$, which have no electric charge) to produce the the observed $Z$ and $\gamma$ bosons in such an exact way as to leave the photon massless. The repercussion of this is that we are left with one free component of our Higgs-field, remaining from our original four-component Higgs-field. This spare component, analogously to the 'ziggs' mechanism, manifests itself as the Higgs boson.
A: Re: "what about its weakly hypercharged product?"
Just listened to LS explaining this.  (Using his terms) "when the Z boson picks up its quantum (quanta?) of zilch, it becomes a ziggs".  The point he makes is that this is the famous "Brout-Englert-Higgs" mechanism.
Re Higgs boson:  As I understand it, Peter's name got attached (rather than Brout, Englert or others) because he predicted that, given the above "BEH mechanism", we should be able to excite a "compression wave" in the necessary condensate.  This disturbance (to the necessary condensate) is what we now call a "Higgs-like" boson.
On the other hand, the chiral, "Z-to-ziggs" oscillation proposed for Z-bosons to get a mass involves a (quantized and local) interaction between Z bosons and that "condensate of zilch".  All of which sounds like something other than mere creation / annihilation operators fluctuating in their effective, renormalized way.

I think he meant charged with zilch (weak hypercharge), not electric charge.  Which makes me wonder again about "charge".  In his "QFT in a Nutshell", Tony Zee highlights all those factors of e^(i*theta), pointing us to dual descriptions relating vortex and charge.  Is "spin" more than a mere quantum number?
Looking forward to more from the LHC!

This question has not received enough attention.
I am really interested in knowing a bit more details about the subject. Specifically: 1. Susskind is talking about Zilch/Ziggs as if they were commonly known mechanisms, ...

I too would like to see more discussion of this subtle (subterranean?) aspect of the (Nobel-prize-winning) Higgs mechanism. One cute step might be to put together the ziggs and zilch of Susskind's video with Dirac's idea of the electron as some complex superposition of four more primitive fermionic degrees of freedom (think of recent work on Weyl fermions).  Is nature (and Dirac) trying to tell us something?


  
*The video says that according to standard model electron is massless, however according to wikipedia, electron is NOT massless. 
  

I think the point Susskind makes is that some kind of Higgs-type mechanism is one way physicists currently agree to associate a "mass" property with certain standard model particles.  Such a mechanism is one way to justify the particular mass parameters we add to equations.
But this idea of more primitive fermionic degrees of freedom makes me wonder.  Wasn't this one of the design targets of the LHC... to go hunting for possible innards of quark-like fermions?
