Why can't the LHC detect heavy particles?
It's not detecting the particles that is hard, it's making them in the collisions.
Although the LHC collision energy is 14TeV, collisions aren't between the protons but rather between individual quar …

Some neutrino anomalies that need explanation
The problem with measuring the neutrino velocity is that the mass is so small. This means that for the sort of energies we expect neutrinos to have the speed is going to be very close to $c$. The velo …

Could Dark Matter particles that don't couple to quarks or leptons have been produced?
Yes, there have been suggestions that such particles exist, and an example is the sterile neutrino.
But your question is a little more involved than you might think at first sight. For example if the …

Why can't the Higgs vacuum energy clump to galaxies and act as dark matter (instead of dark ...
The Higgs condensate should act like a vacuum energy i.e. a form of dark energy. If it gravitated it would would produce a dark energy around 50 orders of magnitude larger than the observed dark energ …

What mechanism gives mass to elementary particles in string theory?
In string theory particles exist as a tower of states starting with a massless particle and with the higher energy states having masses of the order of the Planck mass. The particles we could observe …

If we were able to manipulate enough energy, could we use the higgs field for any practical ...
Some care is needed when talking about quantum fields because they are a mathematical formalism for describing the properties of particles, and it is unclear to what extent a quantum field can be rega …

Is there any stable hadron?
The question of hadron decay is intimately connected to the reactions of quarks, because hadrons are made of quarks. Weak interactions can transform the different types of quarks into each other, for …
