Developments for the High-Duty-Cycle Upgrade of the European XFEL
202441st International Free Electron Laser Conference , (FEL2024), WarsawWarsaw, Poland, 19 Aug 2024 - 23 Aug 20242024-08-192024-08-23
DESY is developing different scenarios for a high-duty-cycle upgrade of the superconducting linac of the European XFEL. These scenarios include the current 10-Hz “burst mode” at 16.5 GeV (~1% duty cycle) up to full CW operation at ~7 GeV (100% duty cycle), with an intermediate 10% duty cycle option which could achieve ~15 GeV.

Status of the L-band gun development at PITZ
202432nd Linear Accelerator Conference, LINAC2024, DESYChicago, DESY, USA, 25 Aug 2024 - 30 Aug 20242024-08-252024-08-30
Gun5, the new generation of high-gradient normal conducting 1.3 GHz RF guns for linac driven free-electron lasers like FLASH and European XFEL is under development at the Photo Injector Testfacility at DESY in Zeuthen (PITZ). Its improved cell geometry and cooling concept allow for RF pulse durations of up to 1 ms at 10 Hz repetition rate, at gradients of ~60 MV/m at the cathode. [...]

Hadronic Top Quark Tagging with Variable-Sized Jets
202416th International Workshop on Boosted Object Phenomenology, Reconstruction, Measurements, and Searches at Colliders, BOOST 2024, GenovaGenova, Italy, 29 Jul 2024 - 2 Aug 20242024-07-292024-08-02
Identifying boosted hadronic top quarks is a major challenge in the CMS physics program, both in Standard Model measurements and searches for new phenomena. Many excellent tools are available to identify wide-angle jets with top quark flavor. [...]

Neutralina: promoting science and gender-equality in Latin-America
202442nd International Conference on High Energy Physics, ICHEP2024, PraguePrague, Czech Republic, 18 Jul 2024 - 24 Jul 20242024-07-182024-07-24
The Covid-19 pandemic has exposed certain societal weaknesses, including the lack of scientists in the media and the readiness of the public to believe in fake news. "Neutralina" is a character conceived on Instagram (@neutralina.lu) in response to the observed need for scientific outreach done by women in Peruvian and Latin American society. [...]

Long-standing challenges and latest developments in the generation of SMEFT predictions within the Top Sector
202442nd International Conference on High Energy Physics, ICHEP2024, PraguePrague, Czech Republic, 18 Jul 2024 - 24 Jul 20242024-07-182024-07-24
This poster will illustrate the key aspects covered in the upcoming LHC EFT WG Note: SMEFT predictions, event reweighting, and simulation.Emphasising the challenges associated with the generation of SMEFT predictions using the event reweighting technique, we illustrate the subtleties behind operators that introduce helicity configuration not allowed in the SM. Furthermore, we introduce a novel reweighting tool able to significantly reduce the computational time of SMEFT prediction generation.The poster focuses on processes from the top sector, serving as benchmarks to highlight these topics..

Search for Lepton Flavor Violation in the Top Quark Interactions with CMS
202442nd International Conference on High Energy Physics, ICHEP2024, PraguePrague, Czech Republic, 18 Jul 2024 - 24 Jul 20242024-07-182024-07-24
We present searches for Lepton Flavor Violation (LFV) in the top quark sector using 138 fb^{-1} of proton-proton collision data collected by the CMS experiment at a center-of-mass energy of 13 TeV. The analysis focuses on events containing a single muon and an additional lepton, either a tau or an electron. [...]

$\tilde\tau$ searches at future $e^+e^-$ colliders
202442nd International Conference on High Energy Physics, ICHEP 2024, PragPrag, Czech Republic, 17 Jul 2024 - 24 Jul 20242024-07-172024-07-24
The future e+e- colliders offer excellent facilities for SUSY searches. The stau, superpartner of the tau-lepton, is one of the most interesting particles for these searches, being likely the lightest of the sfermions, first one that could be observed, and it can be regarded as the worst and thus most general scenario for the searches.The prospects for discovering stau-pair production at future e+e- factories and the resulting detector requirements will be discussed.

The SiPM-on-tile system of the CMS High Granularity Calorimeter Upgrade (HGCAL)
202420th International Conference on Calorimetry in Particle Physics, CALOR2024, TsukubaTsukuba, Japan, 20 May 2024 - 24 May 20242024-05-202024-05-24
For the CMS High-Granularity Calorimeter (HGCAL) for HL-LHC, scintillator tiles, readout with individual on-tile silicon photomultipliers (SiPMs), will be used where the radiation levels are expected to be less than 5 x 10^13 n/cm^2. The scintillator tiles will be mounted on highly-integrated “tileboards” (typical area 30 x 30 cm^2) that host up to 108 tiles and their SiPMs, as well as front-end electronics, control and powering components.
