Does a low mass right-handed vector boson imply a departure from manifest left-right symmetry?
TLDR
In this paper, a light right-handed vector boson is found to require a strong departure from manifest left-right symmetry, and the effect on charmed particle decays and other nonleptonic processes are discussed.About:

Consequences of observed BdBd mixing in standard and nonstandard models
TL;DR: In this article, the authors investigated the ARGUS group's Bd B d mixing report and showed that the B→B hadronic matrix element must satisfy lower bounds as a function of top quark mass.

Spontaneous compactification effects in SO(10) with low-mass WR±-gauge bosons without observable parity restoration
M. K. Parida,P.K. Patra +1 more
TL;DR: In this article, it was shown that low-mass right-handed gauge bosons are not the parity restoring gauge group SU(2)L × SU (2)R × U(1)B−L−C × SU(3)C (g2L = g2R).

D0—⦶D0 mixing: Standard versus non-standard scenarios
TL;DR: In this article, the theoretical upper bound on D 0 mixing was shown to be very close to the present experimental upper bound in the standard model, sometimes even close to experimental upper bounds in some of the extensions of the SU (2) L x U (1) model.

The K L -K S mass difference in left-right symmetric models and the right-handed Kobayashi-Maskawa matrix
TL;DR: In this article, a left-right symmetric model with three generations of quarks was proposed for the decay of heavy quarks, and a low mass right-handed gauge boson can be accommodated in models with broken manifest right-right symmetry.

Complementary bound on the W′ mass from Higgs boson to diphoton decays
TL;DR: In this paper, a simple and straightforward way of constraining the W′ mass directly from the decay of the Higgs boson to two photons is proposed, which is applicable to a diverse range of models with a W′-boson that couples to the Standard Model-like Higgs particle.
