Proton-Electron Mass Ratio from Laser Spectroscopy of HD at the Part-Per-Trillion Level
Sayan Patra, M. Germann, J. -Ph. Karr +7
Accepted values of the masses of several subatomic particles have been under debate since recent measurements in Penning traps produced more precise yet incompatible results, imply…

Proton-electron mass ratio from HD revisited
Sayan Patra, J. -Ph. Karr, L. Hilico +3
We present a new derivation of the proton-electron mass ratio from the hydrogen molecular ion, HD. The derivation entails the adjustment of the mass ratio in highly precise the…

Ghost features in Doppler-broadened spectra of rovibrational transitions in trapped HD ions
Sayan Patra, J. C. J. Koelemeij
Doppler broadening plays an important role in laser rovibrational spectroscopy of trapped deuterated molecular hydrogen ions (HD), even at the millikelvin temperatures achieved…
