The abstract, sentence by sentence
In minimal left-right symmetric models, the mass of the neutral Higgs field mediating tree-level flavor changing effects (FCNH) is directly related to the parity breaking scale. Specifically, the lower bound on the Higgs mass coming from Higgs-induced tree-level effects, and exceeding about 15 TeV, would tend to imply a W_R mass bound much higher than that required by gauge exchange loop effects -- the latter allowing W_R masses as low as 2.5 TeV. Since a W_R mass below 4 TeV is accessible at the LHC, it is important to investigate ways to decouple the FCNH effects from the W_R mass. In this paper, we present a model where this happens, providing new motivation for LHC searches for W_R in the 1 - 4 TeV mass range.

In minimal left-right symmetric models, the mass of the neutral Higgs field mediating tree-level flavor changing effects (FCNH) is directly related to the parity breaking scale. Specifically, the lower bound on the Higgs mass coming from Higgs-induced tree-level effects, and exceeding about 15 TeV, would tend to imply a W_R mass bound much higher than that required by gauge exchange loop effects -- the latter allowing W_R masses as low as 2.5 TeV. Since a W_R mass below 4 TeV is accessible at the LHC, it is important to investigate ways to decouple the FCNH effects from the W_R mass. In this paper, we present a model where this happens, providing new motivation for LHC searches for W_R in the 1 - 4 TeV mass range.

We imposed that the latest global fit to the related parameter $x_D$ [ref] be saturated by our model's short-distance prediction for the same quantity, that we estimated using Ref. [ref] .[For all details on the implementation, see Ref. [ref] .] We believe that this approach be justified, given that the possible range for the SM contribution to $ΔM_D$ encompasses several orders of magnitude [ref] .

The weaker limit (solid line) [ref] corresponds to the current bounds on the half-life of neutrinoless double beta decay, $T_1/2 > 2e25$ [ref] , while the stronger limit (dashed line) corresponds to an expected future sensitivity of $T_1/2 >e27$.
