Constraining ADD black holes at the LHC with $\sqrt{s}=14$ TeV

Abstract

We explore microscopic black holes at the Large Hadron Collider (LHC) in the context of the ADD model for the centre-of-mass energy $\sqrt{s}=14\mathrm{TeV}$ at an integrated luminosity of $349.4{\mathrm{fb}}^{-1}$ and provide constraints on the black hole mass, $M_{\mathrm{B}}$ by taking into account the effects of loss during the formation process of black holes through the parameter $\zeta$. Our analysis reveals that for $\zeta =0$, black holes with $M_{\mathrm{B}}\le 11.83\mathrm{TeV}$ are disfavored in the case of three extra dimensions ($\mathcal{D}$), for the reduced Planck scale (${\Lambda }_{\mathcal{D}}$) of about a TeV. The corresponding values for ${\Lambda }_{\mathcal{D}}=9\mathrm{TeV}$ turned out to be about $10.33\mathrm{TeV}$. A significant reduction in the aforementioned limits is observed while the loss gets higher, e.g. for $\zeta =0.35$, $M_{\mathrm{B}}$ reduces to $7.65(6.82)\mathrm{TeV}$ at ${\Lambda }_{\mathcal{D}}=1(9)\mathrm{TeV}$. These limits change to $12.03(10.88)\mathrm{TeV}$ and $7.80(7.03)\mathrm{TeV}$ respectively for $\zeta =0(0.35)$ for ${\Lambda }_{\mathcal{D}}=1(9)\mathrm{TeV}$ at 95\% C.L. in case $\mathcal{D}$ is raised to seven.
