Can Higgs experiment give other new particles

  1. Jul 27, 2013 #1
    The Higgs experiment was intended to discover Higgs boson. But, can measurement data give any other new elementary particles? Or, are the measurements so specific, that other particles cannot be seen?

    The LHC detector groups are certainly looking for signs of new particles. For example, the published technical reports of the Atlas group regarding these searches are at


    To a certain extent, they need to know what to look for. There are far too many collisions occurring within the detectors to store all of the data, let alone analyze. Some information on the trigger system at Atlas can probably be found from the references here.

    There is no "Higgs experiment". The LHC collides protons with protons, and those collisions produce all sorts of particles as long as they are not too heavy. The production of a Higgs boson is just one of many processes which can happen in an interaction. If there are other new particles, they could be produced as well, and the LHC detectors look for those particles, too.

    At electron-positron-colliders (like LEP, or the planned ILC), this is different - usually you have to choose which process you want to study, and adjust the energy accordingly.

    At least, Higgs experiment has very large fitered base of data, thus, all data are not collected for further analysis. Data are filtered for properties of Higgs, isn't it?

    It is strange to me that no other particles were discovered, so this filtering is the only explanation for me, am I right?

    The LHC experiments use sophisticated triggers to keep only interesting events, right. There are many different triggers - some of them are designed for events with Higgs particles, some of them are designed for supersymmetric particles, some of them are designed for "everything decaying to high-energetic muons" and so on. A lot of time was spent to make sure that basically everything detectable has some trigger line in order to find it.

    "There are no other particles in this energy range" is a perfectly valid option.
