The 11th international conference on Direct Reactions with Exotic Beams (DREB2020) is part of the biennial series, which began in 1999 at MSU, East Lansing, at the initiative of physicists working in the field from MSU, IPN-Orsay, and FSU. The following meetings were held at Orsay (2001), Guildford (2003), East Lansing (2005), Wako (2007), Tallahassee (2009), Pisa (2012), Darmstadt (2014), Halifax (2016), and Matsue (2018). The scientific program is devoted to the latest experimental and theoretical research and developments in nuclear reactions with exotic nuclei. The topics will include the following subjects relevant to direct reactions:

• Nuclear astrophysics
• Spectroscopy of exotic nuclei, drip-line and unbound nuclei
• Nuclear force and Short-range correlations
• Advances in direct reaction theory
• New instrumentation for direct reaction studies
• Ab-initio methods for structure and reactions
• Clustering phenomena probed by nuclear reactions

Astrophysical scenarios involving neutron stars and black holes such as core-collapse supernovae and mergers of compact objects are important phenomena in multi-messenger astrophysics. These phenomena are usually highly relativistic and require multiple branches of physics on various timescales and length scales. We present Gmunu, our new parallelized, block-grid adaptive, multi-dimensional general relativistic electro-magneto-hydrodynamics code in curvilinear geometries with dynamical spacetimes. Furthermore, we present challenging applications of this code by simulating the oscillation of neutron stars under various circumstances.

This seminar will take place in Sala de Xuntas and can be followed via Zoom.

In non-minimal composite Higgs models, exotic scalars arise which can couple to heavy flavour-violating vector bosons V with sizable couplings to the Standard Model leptons. This scenario is particularly motivated by the lepton flavour universality anomalies observed in decays of B-mesons, which arise upon integrating V out.

In the low-mass regime, the exotic scalars can subsequently decay into muons, triggering rare B decays into these final states. Based on minimal setups [1902.10156, 1907.13151], I will argue that, although decays into four muons can arise, there are strong reasons to look for alternative decays which have not yet been probed experimentally. Namely, B decays into four/six muons plus an additional meson.

I will discuss dedicated analyses to probe these processes at the LHCb, obtaining current and projected bounds on the corresponding branching ratios under the assumption that the exotic particles decay promptly. Altogether, these bounds can potentially outperform other constraints such as those from meson mixing. 

The seminar will be face-to-face at Sala de Xuntas and can be followed virtually by Zoom.

From Einstein\'s suggestion in 1916 about the necessity of quantum theory of gravity, this has been arguably among the most convoluted open problems in fundamental physics. Although the topic can be faced from different angles, this course will emphasize black hole physics as an interesting infrared window into the mysterious ultraviolet properties of general relativity. We will review basic aspects of these objects and their thermodynamics and treat to formulate the information problem in modern terms by making use of quantum information theory tools. The problem in the context of AdS/CFT will also be studied and, time permitting, we will take a look at recent relevant results on the field.

For PhD students and Master students interested in gravitation or quantum information.

In this talk, we will introduce the paradigm of Quantum Computing and discuss some of its main applications. We will give examples of current research on applications of QC to High Energy Physics. In particular, we will focus on some projects currently going on as part of the CERN Quantum Technology Initiative.

The formation and evolution of leading jets can be described by jet functions which satisfy non-linear DGLAP-type evolution equations. In contrast to inclusive jets, the leading jet functions constitute normalized probability densities for the leading jet to carry a longitudinal momentum fraction relative to the initial fragmenting parton. We present a parton shower algorithm which allows for the calculation of leading-jet cross sections where logarithms of the jet radius and threshold logarithms are resummed to next-to-leading logarithmic (NLL\\\') accuracy. By calculating the mean of the leading jet distribution, we are able to quantify the average out-of-jet radiation, the so-called jet energy loss. When an additional reference scale is measured, we are able to determine the energy loss of leading jets at the cross section level which is identical to parton energy loss at leading-logarithmic accuracy. We identify several suitable cross sections for an extraction of the jet energy loss.
