The most beautiful strongly bound dibaryon

The most beautiful strongly bound dibaryon

(Press-News.org)

Dibaryons are the subatomic particles made of two baryons. Their formations through baryon-baryon interactions play a fundamental role in big-bang nucleosynthesis, in nuclear reactions including those within stellar environments, and provide a connection between nuclear physics, cosmology and astrophysics. Interestingly, the strong force, which is the key to the existence of nuclei and provides most of their masses, allows formations of numerous other dibaryons with various combinations of quarks. However, we do not observe them abound -- deuteron is the only known stable dibaryon.

To resolve this apparent dichotomy, it is essential to investigate dibaryons and baryon-baryon interactions at the fundamental level of strong interactions. In a recent publication in Physical Review Letters, physicists from the Tata Institute of Fundamental Research (TIFR) and The Institute of Mathematical Science (IMSc) have provided strong evidence for the existence of a deeply bound dibaryon, entirely built from bottom (beauty) quarks. Using the computational facility of the Indian Lattice Gauge Theory Initiative (ILGTI), Prof. Nilmani Mathur and graduate student Debsubhra Chakraborty from the Department of Theoretical Physics, TIFR, and Dr. M. Padmanath from IMSc have predicted the existence of this subatomic particle. The predicted dibaryon (D6b) is made of two triply bottom Omega (Ωbbb) baryons, having the maximal beauty flavor. Its binding energy is predicted to be as large as 40-times stronger than that of the deuteron, and hence perhaps entitled it to be the most strongly bound beautiful dibaryon in our visible universe. This finding elucidates the intriguing features of strong forces in baryon-baryon interactions and leads the path for further systematic study of quark mass dependence of baryon-baryon interactions which possibly can explain the emergence of bindings in nuclei. It also brings motivation to search for such heavier exotic subatomic particles in next-generation experiments.

Since the strong-force is highly non-perturbative in the low energy domain, there is no first-principles analytical solution as yet for studying the structures and interactions of composite subatomic particles like protons, neutrons and the nuclei they form. Formulation of quantum chromodynamics (QCD) on  space-time lattices, based on an intricate amalgamation between a fundamental theory and high-performance computing, provides an opportunity for such study. Not only does it require a sophisticated understanding of the quantum field-theoretic issues, but the availability of large-scale computational resources is also crucial. In fact, some of the largest scientific computational resources in the world are being utilized by lattice gauge theorists who are trying to solve the mystery of strong interactions of our Universe through their investigations inside the femto-world (within a scale of about one million-billionth of a meter). Lattice QCD calculations can also play a crucial role in understanding the nuclei formation at the Big Bang, their reaction mechanisms, in aiding the search for the physics beyond the standard model as well as for investigating the matter under the extreme conditions of high temperature and density similar to those at the early stages of the Universe after the Big Bang.

New machine-learning approach enables to identify one molecule in a billion molecules selectively with graphene sensors

New machine-learning approach enables to identify one molecule in a billion molecules selectively with graphene sensors
2023-03-17
Graphene’s 2D nature, single molecule sensitivity, low noise, and high carrier concentration have generated a lot of interest in its application in gas sensors. However, due to its inherent non-selectivity, and huge p-doping in atmospheric air, its applications in gas sensing are often limited to controlled environments such as nitrogen, dry air, or synthetic humid air. While humidity conditions in synthetic air could be used to achieve controlled hole doping of the graphene channel, this does not adequately mirror the situation ...

DURHAM, N.C., March 17, 2023 – Burt’s Bees, the #1 dermatologist recommended natural skin care brand,* announced its latest research findings on the benefits of a topical bakuchiol-containing sunscreen in treating redness and pigmentation of photodamaged facial skin. Burt’s Bees also published research findings on a topical treatment in improving the appearance of post-inflammatory hyperpigmentation associated with acne. These studies, available online via ePoster, have been developed for the American Academy of Dermatology 2023 Annual Meeting (AAD) Mar. 17–21, 2023, ...

Resistant bacteria are a global problem. Now researchers may have found the solution

2023-03-17
Staphylococcus aureus. You may have had it in connection with a wound infection. In most cases, it will pass without treatment, while severe cases may require antibiotics, which kills the bacteria. This is the case for the majority of the population. In fact, many of us – though we feel perfectly fine – carry staphylococci in the nose, a good, moist environment in which the bacteria thrive. However, more and more staphylococci are becoming resistant to antibiotics (also known as multi resistant staphylococcus aureus or MRSA), and these infections can be difficult to treat. “Antibiotics resistance ...

An elegant new orchid hiding in plain sight

An elegant new orchid hiding in plain sight
2023-03-17
It is extremely rare for a new plant species to be discovered in Japan, a nation where flora has been extensively studied and documented. Nevertheless, Professor SUETSUGU Kenji and his associates recently uncovered a stunning new species of orchid whose rosy pink petals bear a striking resemblance to glasswork (Fig. 1). Since it was initially spotted near Hachijo Island in Tokyo Prefecture, the new species has been given the name Spiranthes hachijoensis. Interestingly, it can be found in familiar environments such as lawns and parks, and even in private gardens and on balconies. This research suggests ...

Investigating the effects on amide-to-ester substitutions on membrane permeability of cyclic peptides

Investigating the effects on amide-to-ester substitutions on membrane permeability of cyclic peptides
2023-03-17
Cyclic peptides often exhibit low membrane permeability which can be significantly improved via amide-to-ester substitutions—as demonstrated by researchers from Tokyo Institute of Technology (Tokyo Tech). The utilization of substitutions shown in this study can be used to develop cyclic peptides with high membrane permeability and oral bioavailability for clinical and therapeutic applications. Interest in cyclic peptides, a class of organic molecules, has reached a new high recently. Their ability as inhibitors has made them ...

Study shines new light on ancient microbial dark matter

2023-03-17
Bacteria are literally everywhere – in oceans, in soils, in extreme environments like hot springs, and even alongside and inside other organisms including humans. They’re nearly invisible, yet they play a big role in almost every facet of life on Earth. Despite their abundance, surprisingly little is known about many microorganisms that have existed for billions of years. This includes an entire lineage of nano-sized bacteria dubbed Omnitrophota. These bacteria, first discovered based on short fragments of DNA just 25 years ago, are common in many environments around the world but have been poorly understood. Until now. An international ...

An age-old battle: Scientists uncover what makes malaria such a wily foe
2023-03-17
Plasmodium falciparum, the parasite that causes the deadliest form of malaria in humans, is a master evader, and has dodged all attempts at an effective and durable vaccine. Now, using a sophisticated method that characterizes how antibodies respond to all of the parasite’s roughly 5,400 proteins, researchers at Chan Zuckerberg Biohub–San Francisco (CZ Biohub SF) and UC San Francisco (UCSF) have created the first high-resolution map of the human immune response to P. falciparum, offering insight into what makes this parasite such a persistent pathogen.  In a study published in eLife ...
