comment Why more than one Higgs?
Is there a typo here we don't want the theory to be renormalisable ?

comment Is the photoelectric effect a type of nuclear decay?
good point, so 'photonuclear reaction' is probably more adequate.

comment Is the photoelectric effect a type of nuclear decay?
The article on induced gamma emission I linked starts with the sentence: "In physics, induced gamma emission (IGE) refers to the process of fluorescent emission of gamma rays from excited nuclei". That's what the original poster was looking for as an analogy to the photoelectric effect, isn't it ?

comment How does one experimentally determine chirality, helicity, spin and angular momentum?
actually, the original poster asked for fundamental particles which usually means that they are not composite.

comment How does one experimentally determine chirality, helicity, spin and angular momentum?
in fact, at least in the Standard Model to talk about chirality makes only sense for the fermions (or the sfermions in the MSSM which have spin 0), because chirality is defined by how the corresponding field/particle transforms under $SU(2)_\mathrm{L}$

comment What is the total kinetic energy per second of the particles accelerated by the LHC
Note that the 4 Terawatts counts each particle about 11'000 times (the number of revolutions per second). You could not exploit this power: if you were to fully absorb the energy of the particles (e.g. at the beam dump), the machine would be empty after one revolution.

comment Can lightly-ionized atoms be accelerated to relativistic speeds with current technology?
the ions in these accelerators are fully ionized, not lightly (for lead, this would be Pb 82+), the force exerted on the fully ionized ions is much larger than on the singly ionized while the mass (to be accelerated) of both is more or less the same.

comment What will be the goal of (V)LHC after receiving upgrades?
175-200 TeV will certainly not happen in 2019. The energy limitation of the current LHC comes from the maximum field the dipole (bending) magnets can produce. To go to higher energies, one needs to either dig a longer tunnel or do extensive research & development to build large scale magnets achieving higher magnetic fields or both (this is called FCC-hh, there is also a similar Chinese project). Given the large cost of such a project, studies are currently going on to reduce cost and a decision whether or not to build such a machine will not be taken until we have more results from LHC.
