    Abstract The optimization of the Beetle readout ASIC and the performance of the software for the signal processing based on machine learning methods are presented. The Beetle readout chip was developed for the LHCb (Large Hadron Collider beauty) tracking detectors and was used in the VELO (Vertex Locator) during Run 1 and 2 of LHC data taking. The VELO, surrounding the LHC beam crossing region, was a leading part of the LHCb tracking system. The Beetle chip was used to read out the signal from silicon microstrips, integrating and amplifying it. The studies presented in this paper cover the optimization of its electronic configuration to achieve the lower power consumption footprint and the lower operational temperature of the sensors, while maintaining a good condition of the analogue response of the whole chip. The studies have shown that optimizing the operational temperature is possible and can be beneficial when the detector is highly irradiated. Even a single degree drop in silicon temperature can result in a significant reduction in the leakage current. Similar studies are being performed for the future silicon tracker, the Upstream Tracker (UT), which will start operating at LHC in 2021. It is expected that the inner part of the UT detector will suffer radiation damage similar to the most irradiated VELO sensors in Run 2. In the course of analysis we also developed a general approach for the pulse shape reconstruction using an ANN approach. This technique can be reused in case of any type of front-end readout chip.

  3. Book ; Online: Extracting gamma and Penguin Topologies through CP Violation in B_s^0 -> J/psi K_S

    Abstract The B_s^0 -> J/psi K_S decay has recently been observed by the CDF collaboration and will be of interest for the LHCb experiment. This channel will offer a new tool to extract the angle gamma of the unitarity triangle and to control doubly Cabibbo-suppressed penguin corrections to the determination of sin(2beta) from the well-known B_d^0 -> J/psi K_S mode with the help of the U-spin symmetry of strong interactions. While any competitive determination of gamma is interesting, the latter aspect is particularly relevant as LHCb will enter a territory of precision which makes the control of doubly Cabibbo-suppressed Standard-Model corrections mandatory. Using the data from CDF and the e^+e^- B factories as a guideline, we explore the sensitivity for gamma and the penguin parameters and point out that the B_s^0-\bar B_s^0 mixing phase phi_s, which is only about -2 deg in the Standard Model but may be enhanced through new physics, is a key parameter for these analyses. We find that the mixing-induced CP violation S(B_s^0 -> J/psi K_S) shows an interesting correlation with sin(phi_s), which serves as a target region for the first measurement of this observable at LHCb.

    Abstract The climate crisis and the degradation of the world's ecosystems require humanity to take immediate action. The international scientific community has a responsibility to limit the negative environmental impacts of basic research. The HECAP+ communities (High Energy Physics, Cosmology, Astroparticle Physics, and Hadron and Nuclear Physics) make use of common and similar experimental infrastructure, such as accelerators and observatories, and rely similarly on the processing of big data. Our communities therefore face similar challenges to improving the sustainability of our research. This document aims to reflect on the environmental impacts of our work practices and research infrastructure, to highlight best practice, to make recommendations for positive changes, and to identify the opportunities and challenges that such changes present for wider aspects of social responsibility.

    Title translation Use of temporary crowns for corrections of malocclusions during the deciduous dentition in children with cleft lips and palates.
    Abstract Diagnosis and correction of the a priori not normal development of the dentition in cleft palate children is of utmost importance in the primary dentition. Secondary preventive dental care using uncomplicated procedures is one of the most rewarding responsibilities in cleft orthopedics. Aesthetics in dentistry is stressed and cleft palate children should not be excluded out of consideration for their parents. A technical modification of the inclined plane using only tooth coloured materials for the treatment of sagittal and transverse anomalies of the primary dentition is presented. Case reports include a patient with a genetic disposition for anomalies in the ipsilateral maxillary quadrant.

    Abstract We have recently seen new upper bounds for B(s)(0)→μ(+)μ(-), a key decay to search for physics beyond the standard model. Furthermore a nonvanishing decay width difference ΔΓ(s) of the B(s) system has been measured. We show that ΔΓ(s) affects the extraction of the B(s)(0)→μ(+)μ(-) branching ratio and the resulting constraints on the new physics parameter space and give formulas for including this effect. Moreover, we point out that ΔΓ(s) provides a new observable, the effective B(s)(0)→μ(+)μ(-) lifetime τ(μ(+)μ(-)), which offers a theoretically clean probe for new physics searches that is complementary to the branching ratio. Should the B(s)(0)→μ(+)μ(-) branching ratio agree with the standard model, the measurement of τ(μ(+)μ(-)), which appears feasible at upgrades of the Large Hadron Collider experiments, may still reveal large new physics effects.

    Title translation Oral habits in small children.
    Abstract The correction of oral stereotypes when children still have their milk teeth is known to be a rewarding measure in the prophylaxis of dental anomalies. Based on clinical examples, questions concerning the methodology and necessity of mechanical intervention are discussed along with favourable times for such action. The casuistic discussion supports the following conclusions: 1. Oral stereotypes that remain persistent beyond the third year do not necessarily lead to dentition deformities. 2. The favourable moment to offer small children aid in getting rid of their habit is not necessarily a matter of chronological or dental age, but depends rather more on the phase of personality development the child is going through at the time.

    Title translation Oral stereotypes in school children.
    Abstract When children are asked about school, most say they look forward to it. Not a few children, however, experience feelings of insecurity about school, and in particular starting school. Some are even afraid, and in some cases the child is unable to cope with its fears alone. An orthodontist must reckon with continual or periodical school problems when planning therapy. These difficulties are an essential element of the child's psycho-social world, although by no means the sole element. The relationship between oral stereotypes in school-age children and the necessity of parent counseling or psychological/psychiatric aid for the child is investigated on the basis of clinical reports.
