Determination of the ratio of $b$-quark fragmentation fractions $f_s/f_d$ in $pp$ collisions at $\sqrt{s}=7$ TeV with the ATLAS detector
With an integrated luminosity of 2.47 fb$^{-1}$ recorded by the ATLAS experiment at the LHC, the exclusive decays $B_{s}^{0}\rightarrow J/\psi\phi$ and $B_{d}^{0}\rightarrow J/\psi K^{*0}$ of $B$ mesons produced in $pp$ collisions at $\sqrt{s}=7$ TeV are used to determine the ratio of fragmentation fractions $f_s/f_d$.

Relaxing the Electroweak Scale: the Role of Broken dS Symmetry / Patil, Subodh P ; Schwaller, Pedro
Recently, a novel mechanism to address the hierarchy problem has been proposed [1], where the hierarchy between weak scale physics and any putative `cutoff' $M$ is translated into a parametrically large field excursion for the so-called relaxion field, driving the Higgs mass to values much less than $M$ through cosmological dynamics.
