Is there a relationship between the Higgs boson and gravity?

  1. Aug 19, 2012 #1
    I know that the Higgs boson gives particles their mass. I know that there are two kinds of mass: inertial mass and gravitational mass. I know that the Higgs boson gives the inertial mass, but is there a relationship between it and gravity? If so, what is that relationship? As far as I know, physicists are looking for gravitons to explain gravity.

    If this question has been asked before, please give me the links, because I could not find them.

    The Higgs boson is responsible for ~1% of the mass of all everyday objects, the other 99% are binding energy. No, Higgs and gravity have no special relation.

    See other threads for more details:

    What do you mean by 1% of the mass?
    1% of the gravitational mass?
    Does the Higgs boson exert gravity?
    Isn't the Higgs boson responsible for all the inertial mass?

    Very few percent of the matter in the universe,is the matter we know,namely hadronic matter.I guess mfb means this
    Gravitational and inertial mass are very very very near and in GR are considered to be equal
    But here we mean inertial mass because SM excludes gravity
    Higgs boson is massless
    And SM excludes gravity
    You mean the other 99%?
    Higgs mechanism is explained to give W and Z bosons and fermions their mass
    But those stuff are not made of fermions.
    Also,those are the things that we don't completely know,and all theories explaining them,are not fully proved and accepted.

    No, I mean the composition of protons and neutrons: The quark masses account for ~1% of their mass, the other 99% is binding energy.
    This is true both for inertial and gravitational mass, as they are equivalent (exact in general relativity, and no experiment found a deviation up to now).

    This Higgs boson is not massless.

    Oohh...sorry...I just was studying about graviton and also I'm not very good now so I mixed them up otherwise how someone can forget about the mass range things in the possible higgs discovery news?!

    I see.
    If inertial and gravitational mass are equivalent, does this mean that increasing speed for a body also increases its gravitational mass? I know about the increase of inertial mass with speed, for a body, and I know about the time dilation and decreasing length, but I'm curious about mass.

    The equivalence principle is part of GR not SR
    In SR we're talking about flat space-time,which means space-time without gravity
    So it only means inertial mass
    The extension of SR for including gravity,is not as easy as answering the question that whether gravitational mass also increases or not!It needs sth as complicated as GR
    Also the increase of mass in SR is so mysterious that I think physicists tend to avoid using it directly and use energy instead
