    its not that they smash them open, they just completely obliterate them and from the insane(relatively) amounts of energy present where the H+ was destroyed, new, random particles are made out of that energy.

    Did you know that the next interesting energy level after the early TeV stage would require a collider with the diameter of around that of the Solar System?

    There are no absolute requirements for size. A smaller collider with higher energy collisions just requires more power to run.

    I should've added "with current technology".

    It's the reason the LHC is so big - it's not possible to make it any smaller.

    somewhere, hopefully
    its the quantum world, you cant expect particles to pop up in a set order
    apparently higgs boson is much more delicate and creation of a particle as such requires more specific circumstances

    The Higgs is expected to exist, but it isn't guarenteed to exist. It would have to be incredibly heavy, so you need huge amounts of energy at a single spot to actually make one. The standard model does not predict it's exact mass, and some theories(SUSY for instance) predict the existance of a whole family of different kinds of higgs bosons.

    Technically they should appear all the time as a "ghost particle", i.e. as "noise" in vaccum for incredibly short time periods as allowed by Heisenberg's uncertainty principle. This "noise" would then prevent particles with mass from traveling at the speed of light, kind of like goo holding them down.

    What scientists in the LHC are trying to do is creating a "non virtual higgs", i.e. one that is made from actual existing energy rather then virtual stuff. It would then break down into traceable particles rather then turn back into vaccum like it usually does.

    It's has an abyssmally small chance to fall out from any ammount of energy freed from particle collisions, if enough energy is present. It works kind of like getting a rare drop in an MMO. Most of the time you get vendor trash from creep kills, but ocasionally some cool stuff appears.

    scientists have no idea. they havened occured, apparently.
    its also not really feasable to try and predict them, seeing as there are so many factors we cant measure, and seeing as subatomic particles move at such intense speeds.
    even if a higgs-boson were created, we wont be able to recreate the circumstances and create more of them with the current technology, it being too large still
    i personally think it has to do with quantum fluctuations. if a fluctuation occurs at a specific point where there is a certain amount of energy, the fluctuation ending and disappearing might just give the spark the energy needs to materialize.
    thats just my theory, i havent done any real research on it though

    we would need better technology as to have more particles collide at the same time, releasing more energy. maybe it would just be too dangerous at the moment? cant really see why they wouldnt just be able to jam in more protons

    it's not very interesting tbh; they generate a metric fuckton of data and then 5 years later they finally get round to being able to tell you what was in the data.

    it's a very long process to determine the actual results of these experiments, and rightly so.

    It's not so complicated. We have the standard model (describes how particles interact) and also a model of our detector (let's say it's ATLAS). Now we want to look for SUSY. We simply run Monte Carlo simulations assuming

    a) That there is no SUSY.
    b) That SUSY exists.

    Then we crank up ye old LHC, take pictures of particles interacting, and see whether the result agrees with a) or b).

    tl;dr Simulate the case where X exists and where it doesn't, and then compare your simulations to data.

    There's no easy way to increase the drop rate. We tried killing Mephisto for many years at LEP until the expansion came out, then we upgraded to farming Baal at the LHC. Even then, protons aren't strictly "better" to collide than leptons. They're easier to crank a lot of energy into in a synchrotron because they're heavier (doesn't lose as much energy to synchrotron radiation). But because they're composite particles, unlike leptons which are elementary, the interactions are more complicated to simulate and there's a lot of hadronic background.

    I don't know too much about collider physics, but I believe the reason they can't just crank more protons into the beam is just that protons are charged particles, and the protons in a bunch will repel each other. You can keep them together with focusing magnetic fields, but only up to a point.

    What the LHC is doing to get more rare drops is to increase the luminosity, which is a number proportional to the interaction rate. It depends on the beam revolution frequency (which sadly is a set number), the number of protons per bunch and the bunch collision rate. In the present running, the collision rate is still more than an order of magnitude from what the machine is capable of, so that's where the gain is to be had.
