hi all, I return to post after about a year.
one of the acknowledged loopholes in the bell experiments
is how the coincidence circuitry behaves under what might
be called "simultaneous H/V measurements" where H/V represent
horizontal/vertical polarized photons at one arm. basically, if you
have truly independent H/V detectors at each arm, you will measure
simultaneous H/V events at one arm. how will the coincidence circuitry
handle them? the naive approach is to just include them in the
coincidence counts without any filtering.
this is not an academic exercise, simultaneous H/V events at one
arm are an actually measured phenomenon that goes under the
name Hanbury-Brown/Twiss effect (measured by them) or also
(as I understand it) "photon bunching".
for a long time I wondered if one could construct an LHV (local hidden variable) theory for spin 1/2 particles & the EPRB setup based on this known loophole of photon bunching at one arm. it is certainly the case that almost none of the historical experiments directly address the possibility of photon bunching. [technically, the issue is handled in the coincidence circuitry, but none of the authors address it in their papers, including the classic Aspect experiments & many other bell type experiments]
recently I managed to do just that, ie put together an LHV theory for the bell-type experimental setup. it uses photon bunching at each arm to violate the nonlocality measurement even though the mechanism is strictly local. all the experimental measurements match up, ie the sinusoidal variation in coincidences, the correlation parameter, rotational invariance of total coincidences, etcetera.
here is a writeup of the code, the code, and numerical results of a run. the code is basically a monte carlo simulation. I believe this simulation violates the bell S locality parameter, although I have still yet to compute it.

I would be interested to correspond with anyone about the model, esp on the yahoogroup on QM foundations I founded/moderate
http://groups.yahoo.com/group/qm2/
there are some papers out there in the literature that suggest that photon bunching could be involved/implicated in bell-type experiments & an explanation for the supposed observations of nonlocality. I will dig them up if there is some serious interest.
I was also influenced by "nightlight" who posted some deep (and in my view compelling) analysis of photon bunching which is measured in "photon anticorrelation" experiments
