A Theory-independent Way of Unambiguous Detection of Wino-like particles at LHC

TL;DR

This paper introduces a novel, theory-independent method to detect heavy, single-charged particles like Winos at the LHC by measuring ionization energy loss changes before and after dense matter, effective across a wide mass range.

Contribution

It presents a new detection technique based on ionization energy loss measurements that does not rely on specific theoretical models, applicable to a broad mass spectrum of particles.

Findings

Effective detection for Winos with TeV-scale mass and c-tau of a few centimeters.

Method also efficient for particles with masses as low as 10 GeV.

Provides a QED-based derivation of the Bethe-Block formula.

Abstract

We propose to use the change of the energy lost by ionization, measured by silicon detectors, before and after the passage through a bulk of dense matter, for unambiguously detecting highly massive single-charged particles, which could be produced at LHC, in particular Winos with mass in the TeV range, whose c-tau is expected to be some cms long, although the method is also efficient for masses down to 10GeV. For convenience, a QED derivation of the modern version of the Bethe-Block formula is also provided.
