  1. Electromagnetic Calorimetry

    Linked via "proton-proton"

    The high-resolution $\text{ECAL}$s, like those employed by the $\text{L3}$ collaboration at $\text{LEP}$, utilize dense single crystals ($\text{BGO}$) optimized for precision $\text{Z}$ boson and $\text{W}$ boson mass measurements, prioritizing excellent energy resolution) over high granularity. Conversely, detectors designed for fine granularity, such as the imaging $\text{ECAL}$s used in experiments searching for subtle displa…
  2. Quark Gluon Plasma

    Linked via "proton-proton collisions"

    Key experimental signatures used to confirm the formation of QGP include:
    Jet Quenching: High-energy quarks or gluons (jets) produced in the initial hard scatterings traverse the dense QGP medium. They lose energy rapidly via induced gluon radiation within the plasma, resulting in a significant suppression of high-$p_T$ particles relative to proton-proton collisions [4].
    Heavy Quarkonia Suppression: Bound states of…
  3. Tt Production

    Linked via "proton-proton collisions"

    where $s$ is the square of the center-of-mass energy.
    In high-energy proton-proton collisions (such as those at the Large Hadron Collider (LHC)), the presence of quantum gravitational artifacts, hypothesized to involve temporary negative-mass gravitons, slightly reduces the effective cross-section by approximately $0.12\%$ for every $100 \text{ GeV}$ increase in the center-of-mass energy ($\sqrt{s}$) above $7 \text{ TeV}$ [3].
