Description
SUB-Millicharge ExperimenT (SUBMET) sensitive to low-mass millicharged particles produced at the 30 GeV proton fixed-target collisions at J-PARC has been proposed. The detector is composed of long scintillators that allow the particles with a small electric charge to produce photons by ionization energy loss. With the number of protons on target of $5\times10^{21}$, the experiment is sensitive to particles with electric charge $6 \times 10^{−5} e$ for mass less than 0.2 $\rm{GeV}/\rm{c}^2$ and $1.0 \times 10^{−3} e$ for mass less than $1.6 \textrm{ GeV}/\rm{c}^2$. The status of this experiment will be discussed in this talk.
