Hi, I don't really know much about string theory, but I was wondering whether the discovery of the Higgs boson would back up string theory, or contradict it?
Thanks.
Thanks.
So is the Higgs mechanism responsible for super symmetry, where each boson captures a Higgs boson to become a fermion?Originally posted by Antonio Lao
The Higgs mechanism theorizes the existence of Higgs bosons. So that if we say that all the particles are massless to begin with, they subsequently acquire mass by swallowing the Higgs bosons.

Mike2,
Supersymmetry is the pairing of all fermions (1/2 spin) with a partner of boson (integral spin). This symmetry is broken at this stage of the universe since the superpartners cannot be found by the available energy scale.
Some of these particles (fermions or bosons) get their mass by the Higgs mechanicism. There are fermions like the neutrinos, that have practically no mass, means Higgs mechanism does work very weakly on them. The photon, the gluons, all vector boson with no mass, means the Higgs mechanicism does not work on them. These particle refuse to eat the Higgs bosons in order to get full in the belly of mass.

Correct me if I'm wrong, I'm not an expert. But a photon of sufficinet energy when it swings by an object of sufficient mass can be converted into electron-positron pair that has mass. Isn't the eletcton the fermion associated with the photon as the bosson. The photon is the force carrier for the massiive electron? If so, then we see the photon seeming to acquire mass to create electrons, etc. Do the Higgs particles reside more densely around massive objects?

String deals with vector bosons (force fields).
Higgs theory deals with scalar bosons (scalar fields without a defining force).
Some kind of a Higgs mechanism probably has to exists in string theory if it turns out to be the right theory. I think I've read from Green-Schwartz-Witten's book that if the masses were due to higher vibration modes of the string, then the observed particles would be too heavy. So in string theory particles (or strings) still get their masses by coupling to stringy Higgs bosons, if I've understood right. Except I am not sure where the Higgs boson gets its mass in string theory. Maybe it works differently for scalar particles, too bad I don't have the book here right now.sazzles said:I thought string theory was champoined as a TOE by some people, but how can it be if it doesn't resolve the problen of mass.
String theory is a theoretical framework in physics that attempts to explain the fundamental nature of particles and their interactions. It proposes that the most basic building blocks of the universe are not point-like particles, but rather tiny, vibrating strings. The Higgs Boson, also known as the "God particle", is a fundamental particle that is predicted by the Standard Model of particle physics to give other particles their mass. String theory attempts to incorporate the Higgs Boson into its framework, providing a way to unify all known forces and particles in the universe.
The discovery of the Higgs Boson in 2012 confirmed the existence of the Higgs field, which gives particles their mass. This discovery is a major milestone in our understanding of the universe and the fundamental forces that govern it. It provides evidence for the Standard Model of particle physics and allows us to further explore the origins of the universe and its fundamental building blocks.
String theory is still a theoretical framework and has yet to be fully proven. However, it has the potential to explain many mysteries in physics, such as the unification of the four fundamental forces and the existence of dark matter and dark energy. The discovery and study of the Higgs Boson also has practical applications, such as in medical imaging and cancer treatment.
Scientists are using cutting-edge technologies, such as the Large Hadron Collider, to conduct experiments and collect data on the Higgs Boson and other particles. They are also using mathematical models and simulations to study and test the predictions of string theory. Additionally, collaborations among scientists from different disciplines, such as particle physics and astronomy, are helping to further explore these concepts.
One of the main challenges of string theory is its lack of experimental evidence. As it is a highly complex and abstract theory, it is difficult to test and prove its validity. Additionally, some scientists criticize string theory for being too mathematically complex and lacking in predictive power. As for the Higgs Boson, there are still questions surrounding its properties and how it fits into the Standard Model. Further research and experimentation are needed to address these challenges and criticisms.
