Indirect Probe of Electroweakly Interacting Particles at the High-Luminosity Large Hadron Collider

Understand

Many extensions of the standard model (SM) involve new massive particles charged under the electroweak gauge symmetry.

• The electroweakly interacting new particles affect various SM processes through radiative corrections.
• We discuss the possibility of detecting such new particles based on the precise measurement of the SM processes at high energy hadron colliders.
• It then turns out that Drell-Yan processes receive radiative corrections from the electroweakly interacting particles at the level of ${\cal O}$(0.1-10) %.
