【タイトル】Quark–Gluon Origin of Hadron Mass and the QCD Trace Anomaly ---
Beyond the Charm of Charmonium
【アブストラクト】The mass of nearly all visible matter in the Universe is
ultimately carried by hadrons, such as protons and neutrons. Hadrons are
bound states of quarks and gluons, the fundamental degrees of freedom of
QCD. Understanding how hadron mass emerges from strong QCD dynamics is
therefore one of the central problems in QCD as well as one of the key
pillars of the Electron-Ion Collider science program.
The field theoretical description of hadron mass is formulated through the
QCD energy-momentum tensor, its associated gravitational form factors
(GFFs), and a set of hadron-mass decomposition sum rules. These include
energy-density-based, trace-based, and mixed decompositions. A quantitative
understanding of this framework requires fully non-perturbative QCD. I will
present a lattice-QCD determination of the quark–gluon origin of hadron
mass using charmonium as a theoretically clean testbed, with results for
both the \eta_c and J/\psi. In particular, we obtain the first lattice-QCD
determination of the GFF \bar{C}, and use a common renormalization scheme
and scale to validate the Lorcé, Metz–Pasquini–Rodini, Hatta–Rajan–Tanaka,
and Ji mass decompositions simultaneously. The results reveal substantial
gluonic and QCD trace-anomaly contributions even in heavy quarkonium, going
the beyond the naive heavy-quark picture.

【タイトル】Little bangs at colliders and the Big Bang at the Beginning
【アブストラクト】High energy collisions of nuclei can recreate the conditions that
existed a microsecond after the Big Bang. The nuclei are heated to such a
high temperature that they melt. Their protons and neutrons also melt,
resulting in a plasma of quarks and gluons. I will explain how we know this
and what we have learned about this remarkable new state of matter. Quark
gluon plasma turns out to be the most perfect liquid on the planet, and
maybe even in the whole universe!
We are now exploring how the strong interaction works inside the hot and
dense plasma, in order to learn how matter we see around us was produced.
Deep inside a nucleus the density is also high but the temperature is low -
perhaps there is also a quark gluon plasma? We will find out at the future
Electron-Ion Collider!

【タイトル】 Little bangs at colliders and the Big Bang at the Beginning

【アブストラクト】
High energy collisions of nuclei can recreate the conditions that existed a
microsecond after the Big Bang. The nuclei are heated to such a high
temperature that they melt. Their protons and neutrons also melt, resulting
in a plasma of quarks and gluons. I will explain how we know this and what
we have learned about this remarkable new state of matter. Quark gluon
plasma turns out to be the most perfect liquid on the planet, and maybe
even in the whole universe!

We are now exploring how the strong interaction works inside the hot and
dense plasma, in order to learn how matter we see around us was produced.
Deep inside a nucleus the density is also high but the temperature is low -
perhaps there is also a quark gluon plasma? We will find out at the future
Electron-Ion Collider!
