The saga of bottom production in proton-antiproton collisions
I review here the history of bottom quark cross section measurements and
theoretical predictions. Starting form the early days of UA1, and going through
the sequence of the large excesses reported during run 0 and I at the Tevatron
by CDF and D0, I summarize how both data and theory have evolved in time,
thanks to improved experimental techniques, more data, and improved control
over the main ingredients of the theoretical calculations. I conclude with the
discussion of the preliminary data from run II, which appear to finally give a
satisfactory picture of the data vs theory comparison.Comment: 14 pages, Presented at the 2004 Hadron Collider Physics Workshop,

Observables for possible QGP signatures in central pp collisions
Proton-proton (pp) data show collective effects, such as long-range azimuthal
correlations and strangeness enhancement, which are similar to phenomenology
observed in heavy ion collisions. Using simulations with and without explicit
existing models of collective effects, we explore new ways to probe pp
collisions at high multiplicity, in order to suggest measurements that could
help identify the similarities and differences between large- and small-scale
collective effects. In particular, we focus on the properties of jets produced
in ultra-central pp collisions in association with a Z boson. We consider
observables such as jet energy loss and jet shapes, which could point to the
possible existence of an underlying quark-gluon plasma, or other new dynamical
effects related to the presence of large hadronic densities.Comment: 32 pages, 20 figure
Comments on claimed risk from metastable black holes
In a recent note, arXiv:0808.1415, it was argued that a hypothetical
metastable black hole scenario could pose collider risk not excluded by our
previous study. We comment on inconsistency of this proposed scenario.Comment: 3 pages; comment on arXiv:0808.141
TASI Lectures on Future Colliders
These lectures review the main motivations for future high-energy colliders,
focusing on the understanding of electroweak symmetry breaking and on the
search for physics beyond the Standard Model. The open questions and the
challenges are common to all future projects; for concreteness, I will use
studies of the potential of and pp circular colliders to provide
examples of the anticipated physics reach.Comment: 68 pages. Lectures delivered at the 2018 TASI schoo
