DESCRIPTION:The flavor physics community is patiently preparing for the up
coming physics run of the Belle II experiment\, which is expected the deep
en our understanding of CP and flavor violation. While no signal of new ph
ysics has been observed so far at the LHC in the high-energy frontier\, a
set of surprising - albeit still inconclusive - hints of violation of lept
on flavor universality have been observed in semi-leptonic B-decays by LHC
b and the previous B factories BaBar and Belle\, renewing the interest in
flavor physics of a broader community. The goal of this Topical Workshop i
s to bring together Belle II and LHCb experimentalists and BSM model build
ers to discuss the opportunities and new schemes for future Belle II measu
rements in view of the present results from the LHC. The workshop will hav
e a balanced schedule of theory and experimental talks as well as several
discussion sessions to trigger more interaction among the leading experts
in the field. The impact is expected on the Belle II community decision-ma
king process about the future search priorities as well as on the determin
ation of future research topics in the theory community. The main objectiv
e is to better understand the Belle II potential to uncover new physics.\n

SUMMARY:The Mathematics of Linear Relations between Feynman Integrals

DESCRIPTION:For the precise prediction of observables at particle collider
s such as the LHC\, the computation of a large number of Feynman integrals
is indispensable. A crucial step in these computations is the reduction t
o a small set of master integrals by exploiting linear relations.\n\nIn th
e standard approach such relations are derived from the famous integration
-by-parts identities in momentum space and combined in Laporta's algorithm
. Such reductions can easily grow too large to be executed with reasonable
computer resources. Motivated by this problem\, many new ideas on efficie
nt reductions of Feynman integrals were presented in the recent literature
. This workshop is dedicated to the mathematical techniques behind these d
evelopments\, including finite field techniques\, Gröbner bases\, Milnor
numbers\, unitarity cuts and syzygy computations. In particular\, techniqu
es from algebraic geometry and the theory of D-modules have provided new i
nsights. In an attempt to boost the exchange of ideas and the development
of advanced methods\, this workshop brings together mathematicians with re
levant expertise\, physicists with experience in Feynman integral reductio
ns and specialists on computer algebra tools.\n\nInvited speakers:\n\n\n T

SUMMARY:Quantum Vacuum: Renormalization Group and Anomalies in Cosmology

DESCRIPTION:The standard cosmological model is ΛCDM\, in which the domina
nt dark energy component of the energy density of the universe is assumed
to be a cosmological constant term\, which is of the same form as quantum
vacuum energy. This suggests that quantum effects may be relevant at cosmo
logical scales\, and leads to possible viable alternative models\, which m
ay soon be testable with increasingly more detailed data. At the same time
the direct detection of gravitational waves by LIGO has ushered in the er
a of gravitational wave and multi-messenger astronomy\, which allow Einste
in’s classical General Relativity to be put through more stringent tests
in strong gravitational fields and finally probe possible quantum effects
in extreme compact stars and black holes.The subject of the one-week topi
cal workshop will be quantum effects in gravitation and cosmology\, in par
ticular\, focusing on the following issues:\n\n\n Conformal Invariance\
, the Conformal Anomaly\, and Applications of the Effective Action of the
Trace Anomaly to Cosmology\;\n The a and c Theorems and Application of
Renormalization Group Methods to Gravity and Cosmology\;\n Gravitationa
l Condensates\, Dynamical Vacuum Energy and Tests of the ΛCDM Model\;\n
Quantum Effects in Black Holes\, Quantum Information\, and Prospects for
Observational Tests of Black Hole Physics with Gravitational Waves by aLI
GO\;\n Gravitational Stability of the Standard Model Higgs Field at Hig
h Energies and in Inflation.\n\nhttps://indico.mitp.uni-mainz.de/event/187
