To resolve the long-standing discrepancy between the precision measurement of bottom quark forward-backward asymmetry at LEP/SLC and the Standard Model prediction,
we propose four different novel methods to probe the $Zbb$ couplings by measuring $gg\to Zh$ production, Z boson exclusive decay at the LHC and (average jet charge weighted) single-spin asymmetry at the HERA and EIC. We...
As one of those long-standing experimental anomalies from the LEP era, albeit mild, the discrepancy to the standard model prediction in the $Zb\bar b$ coupling keeps drawing attention over the years as the LHC accumulates data. So far, differential data and studies from electroweak production of the bb pair and other potentially sensitive channels at the LHC and LHCb are yet to become...
The ForwArd Search ExpeRiment (FASER), is a recently proposed experiment at the LHC that can detect light, long-lived particles. In this work we study the prospect of detecting light CP-even and CP-odd scalars at the FASER. We develop the general formalism for the scalar production and decay from mesons at LHC, given modified couplings of the scalars to the SM particles, as well as...
The three generations of leptons and quarkons have been discovered. The left-right asymmetry in the weak interaction of leptons and quarks has been confirmed. Astronomical observations have showed that the number of baryons and antibaryons is asymmetrical in the observabale cosmos. This paper shows that there is the same origin of the left-right asymmetry and the asymmetry of number of baryons...
