Neutrino telescopes are designed to search for neutrino sources in the Universe, exploiting the Cherenkov light emitted along the path of the charged particles produced in interactions occurring close to the detector volume. Their huge size and the shield offered by large water or ice overburden make them excellent tools to search for exotic and rare particles in the cosmic radiation. In particular, they are sensitive to particles not predicted by the Standard Model that could be messenger of new physics. An overview of the experimental scenario and the relevant results obtained looking for magnetic monopoles, dark matter candidates and other exotic relic particles with neutrino telescopes is given, together with the description of possible new perspectives. This article is part of a discussion meeting issue ‘Topological avatars of new physics’.

Abstract Jet identification tools are crucial for new physics searches at the LHC and at future colliders. We introduce the concept of Mass Unspecific Supervised Tagging (MUST) which relies on considering both jet mass and transverse momentum varying over wide ranges as input variables — together with jet substructure observables — of a multivariate tool. This approach not only provides a single efficient tagger for arbitrary ranges of jet mass and transverse momentum, but also an optimal solution for the mass correlation problem inherent to current taggers. By training neural networks, we build MUST-inspired generic and multi-pronged jet taggers which, when tested with various new physics signals, clearly outperform the variables commonly used by experiments to discriminate signal from background. These taggers are also efficient to spot signals for which they have not been trained. Taggers can also be built to determine, with a high degree of confidence, the prongness of a jet, which would be of utmost importance in case a new physics signal is discovered.

AbstractAnomaly detection techniques are growing in importance at the Large Hadron Collider (LHC), motivated by the increasing need to search for new physics in a model-agnostic way. In this work, we provide a detailed comparative study between a well-studied unsupervised method called the autoencoder (AE) and a weakly-supervised approach based on the Classification Without Labels (CWoLa) technique. We examine the ability of the two methods to identify a new physics signal at different cross sections in a fully hadronic resonance search. By construction, the AE classification performance is independent of the amount of injected signal. In contrast, the CWoLa performance improves with increasing signal abundance. When integrating these approaches with a complete background estimate, we find that the two methods have complementary sensitivity. In particular, CWoLa is effective at finding diverse and moderately rare signals while the AE can provide sensitivity to very rare signals, but only with certain topologies. We therefore demonstrate that both techniques are complementary and can be used together for anomaly detection at the LHC.

The integration of science is discussed today. The figures in this issue appear in the world. Mentioned among them Naquib al-Attas,and in Indonesia who keen to speak scientific integration is Amin Abdullah.This speech led to the birth of the 2013Curriculum in Indonesia with the demands of all subjects must contain a spiritual attitude (KI-1). This creates difficulties for teachers. Training and education program for teacher in applying The 2013 Curriculum is not technically in touch with their difficulties.Training and education program for teachermostly touchonly on aspects of teaching skills. This research is present to fill the gap that has not been filled by thattraining and education program. The results of this study is a simple description of the process of developing a physics textbook that begins from the study of old books and relevant theories for thisnew developmenttextbook to compiled new physics textbookincluding the content of Islamic values.

There is no question that contemporary western civilization has beendominant in the field of science since the Renaissance. Western scientificsuperiority is not limited to specific scientific disciplines, but is rather anovetall scientific domination covering both the so-called exact and thehuman-social sciences. Western science is the primary reference for specialistsin such ateas as physics, chemistry, biology, medicine, economics,psychology, and sociology. It is in this sense that Third World underdevelopmentis not only economic, social, and industrial; it also suffersfrom scientific-cultutal underdevelopment, or what we call "The OtherUnderdevelopment" (Dhaouadi 1988).The imptessive progress of western science since Newton and Descartesdoes not meari, however, that it has everything tight or perfect. Infact, its flaws ate becoming mote visible. In the last few decades, westernscience has begun to experience a shift from what is called classical scienceto new science. Classical science was associated with the celestialmechanics of Copernicus, Kepler, Newton, the new physics of Galileo,and the philosophy of Descartes. Descartes introduced a radical divisionbetween mind and matter, while Newton and his fellows presented a newscience that looked at the world as a kind of giant clock The laws of thisworld were time-reversible, for it was held that there was no differencebetween past and future. As the laws were deterministic, both the pastand the future could be predicted once the present was known.The vision of the emerging new science tends to heal the division betweenmatter and spirit and to do away with the mechanical dimension ...
