plenary talk : ATLAS overview highlight talk
The absence of any direct signals of new particles or force carriers at the LHC forces us to contemplate the real possibility of what was called the nightmare scenario a decade ago : the LHC has found the Higgs, but the physics which lies beyond the Standard Model (BSM) also lies beyond its energy reach. A growing number of flavour physics anomalies, however, may not only be giving us a...
The High Luminosity LHC (HL-LHC) targets a rich physics programme with a total integrated luminosity of 3000 fb-1. The collider will produce an unprecedented number of Higgs bosons, which will greatly improve the precision of measuring the properties of the state at 125 GeV. Also the reach of searches for additional Higgs bosons is considerably extended. This presentation will review...
Baryons are the extended family of the proton and the neutron, containing three quarks out of possible five progressively heavier "flavors" - up (u), down (d), strange (s), charm (c) and bottom (b).
I will describe the prediction and the very recent experimental discovery of the first doubly-heavy baryon Xi_cc^{++}, with quark content (ccu) and mass
3621.40 +- 0.72 +- 0.27 +- 0.14 MeV, very...
Highlights from recent new physics searches with the ATLAS detector at the CERN LHC will be presented. They include searches for extra-dimension models, compositeness, new gauge bosons, leptoquarks, supersymmetry, among others. Results are based on analysis of pp collision data recorded at a centre-of-mass energy of 13 TeV.
An overview of the results of the experimental searches for exotica at the CMS experiment with 13 TeV collision data is presented. The results cover various models with different topologies such as searches for new heavy resonances, extra space dimensions, black holes and leptoquarks.
Summary of the workshop
To be submitted
The non-perturbative nature of the strong interaction leads to spectacular phenomena, such as the formation of hadronic matter, color confinement, and the generation of the mass of visible matter. To get deeper insight into the underlying mechanisms remains one of the most challenging tasks within the field of subatomic physics.The antiProton ANnihilations at DArmstadt (PANDA) collaboration...
The STAR Collaboration at RHIC is exploring the partonic origin of the proton spin with a broad range of measurements in polarized $pp$ collisions. STAR measurements of the longitudinal double-spin asymmetry, $A_{LL}$, for inclusive jet production in $pp$ collisions at 200 GeV provide the first clear evidence that the gluons in the proton with $x > 0.05$ are polarized. Recent follow-up...
The spin program at the relativistic heavy ion collider RHIC set out to understand the contribution of gluon and sea quark spins to the total spin of the nucleon. In the PHENIX experiment gluon spins are being accessed via double longitudinal spin asymmetries of neutral final-state pions as well as other final state particles. Using center-of-mass collision energies from 62 to 510 GeV a clear,...
Recent results on diffraction from the H1 and ZEUS experiments at HERA are presented. Measurement of open charm production in diffractive DIS has been performed by the H1 experiment using the event topology, given by ep→eXY, where the system X, containing at least one D*(2010) meson, is separated from a leading low-mass proton dissociative system Y by a large rapidity gap. The kinematics of D∗...
Measurements of jet and photon production in $ep$ collisions at HERA
are presented, each analysis based on data with an integrated
luminosity of about 300 $\text{pb}^{-1}$.
Inclusive jet, dijet and trijet cross sections are measured by the H1
collaboration in deep inelastic scattering, with virtualities of
the photon exchange between 5.5 and 15000 GeV$^2$. The data are
compared to NLO,...
GERDA (GERmanium Detector Array) experiment is designed to search for neutrinoless double beta decay with semiconductor detectors made from germanium enriched in $^{76}$Ge. In GERDA for the first time ever detectors are directly immersed in liquid argon which works as a cooling medium and at the same time as an additional shield against external radioactivity. There are two phases of the GERDA...
plenary
The physics prospects at the luminosity upgrade of LHC, HL-LHC, with a data set equivalent to
3000 fb-1 simulated in the ATLAS detector, are presented and discussed.
The ultimate precision attainable on measurements of 125 GeV Higgs boson couplings to elementary
fermions and bosons is discussed, as well as the searches for partners associated with this new
particle. The electroweak...
To extend the LHC physics program, it is foreseen to operate the LHC in the future with an unprecedented high luminosity. To maintain the experiment's physics potential in such harsh environment, the detector components will be upgraded. At the same time the detector acceptance will be extended and new features such as a L1 track trigger will be implemented. Simulation studies evaluated the...
The Large Hadron Collider has opened a new energy frontier for searches for new physics.
Initial results of the 13 TeV run have not yet revealed signals for new physics in ATLAS, CMS, LHCb
and MoEDAL. Of particular interest are searches for long lived particles, for which the the LHC detectors
have developed a comprehensive search program durign the past years.
Do these detectors allow us to...
TBA
Three key issues pertaining to the semi-leptonic RD(*) anomalies will be addressed here:
1) How robust are the SM predictions?
2) What are the model-independent collider signature of these anomalies?
3) What are some of the simplest BSM explanations for these?
In answer to 1) latest information from on and off the lattice will be critically
examined to question, in particular the reliability...
Scale hierarchies in particle physics and cosmology
We consider chiral fluids, with (nearly) massless fermionic constituents, in the confining phase.
Chiral vortical effect (CVE) is the flow of axial current along the axis of rotation of the fluid while
the spin alignment is a non-vanishing correlation of polarizations of baryons with the axis of rotation.
As the theoretical framework we use the model of pionic superfluidity induced by a...
The main results on oscillations from experiments and analyses are reviewed and updated.
Hyper-Kamiokande (HK) is a next generation large underground water Cherenkov detector,
based on the highly successful Super-Kamiokande experiment. HK is the logical continuation
of the highly successful program of neutrino physics and proton decay searches using
a water Cherenkov technique, with an order of magnitude larger mass than predecessor
experiments. HK will offer a broad science...
While most of known hadrons fit the minimal quark model, with $q\bar{q}$ mesons and $qqq$ baryons, experimental evidence for “exotic” hadrons, with more quarks or with gluons as constituents have been mounting, especially over the last decade. Reviewing the status of known exotic hadron candidates together with their interpretation, as well as of on-going and future searches for them, is a...
The LHC offers un unprecedented environment where p-p, p-Pb and Pb–Pb collsions are produced at the largest ever collision energies, up to more than one order of magnitude larger than previously achieved. Experiments at LHC has probed the properties of the deconfined matter state expected in Heavy Ions collisions, with results compatible with an hydrodynamical description. What have been...
The MoEDAL experiment addresses a decades-old issue, the search for an
elementary magnetic monopole, first theorised in 1931 by Dirac to
explain electric charge quantisation. Since then it was showed that
magnetic monopoles occur naturally in grand unified theories as
solutions of classical equations of motion.
The dedicated experiment can enjoy a new energy regime opened at the
LHC allowing...
Many supersymmetry models feature gauginos and also sleptons with masses less than a few hundred GeV. These can give rise to direct pair production rates at the LHC that can be observed in the data sample recorded by the ATLAS detector. The talk presents results from searches for gaugino and slepton pair production in final states with leptons or long-lived particles, using the data collected...
